react-big-calendar bug when clicking on show more events

I'm using react-big-calendar (in my next.js project) and as you can see in the image above I'm displaying events on it and I have a bug that I can't understand why its happening.
When I press on the +3 more (which shows me all the events happening on the given day) then the dropdown menu that you can see on the top right image opens and then instantly closes and even if I change page it still gives me the same bug and it happens to all the dropdowns that I have on the website I'm working on.
Now one "hack" is to make the min height of the calendar bigger (I can make it 900px instead of the current 700px) so that all 4 events are shown directly instead of showing the +3 more but the problem with this "hack" is that imagine I have A LOT of events on a given day then I would need to set the min height to really really big number which is undesirable.
Note that the bug disappear if I reload the page but obviously I just can't force the user to reload every time he wants to see more events on a given day.
Which version of React-Big-Calendar are you using? Older versions of RBC used an anchor tag, for the 'more', that had an href="#". I could see that causing issues like this. Current version has replaced this code with a 'button' component styled to look like an anchor.

Why does the first button pressed shrink in codenameone?

I am a novice programmer working on a project that has buttons change color when pressed (among other things). I am having a problem that the first button I click shrinks (the padding increases?) when it is clicked, but it still works and does everything it is supposed to. I have tried looking through theme.res to find a way to stop the button from shrinking when pressed and I have tried looking for an answer online, but have not found a solution. Thanks!
In the Resource Editor(theme.res), go to "Themes" -> "Unselected" tab. Right click over the style you use for the button and press Derive All.

Why hover to element and click submenu does not work when browser is opened full screen?

I am working on a page where a left hand main menu has submenus. I try to hover to the main menu item, and it will show the submenu, and then I will click the submenu.
I am using below code:
#FindBy(id = "xxx")
private WebElementFacade mainmenu;
#FindBy(id = "yyy")
private WebElementFacade submenu;
Actions builder = new Actions(getDriver());
builder.moveToElement(mainmenu).perform();
submenu.waitUntilClickable().click();
I've tried other ways like:
action.moveToElement(mainmenu).moveToElement(submenu).click().build().perform();
It seems the problem is: when the test is performed when browser is in full screen, i.e.
driver.manage().window().maximize();
the main menu sometimes flash very quickly as if it's clicked really fast and recede, other times it appears not clicked or hovered to at all.
Because this hover and click active happens immediately after user navigate to the page, I add wait for element on the main menu, but it does not seem to work.
Any ideas how to solve the problem? I do not understand why it happens only when browser is in full screen mode. The only reason I can think of is the main menu element need more time to load.
EDIT:
Btw, the issue is very severe in Chrome. Firefox is better, but not 100% working either. It seems that even a simple hover:
mainmenu.waitUntilPresent();
Actions builder = new Actions(getDriver());
builder.moveToElement(mainmenu)perform();
does not always make the main menu display its submenu. I do not understand why it does not work.

Ionic - Wrong tab active after changing tabs template

I am learning Ionic and I am stuck in one place because I want to change my default tabs layout to other one.
When I change to state where I reload my tabs layout, in new layout there is always selected second one, no matter what I do... I want first tab to be selected.
Here is plnkr. Go to friends, click one and look on tabs at bottom. Second one is active :(
$ionicTabsDelegate is not working (Or I have done something wrong)

Do you have any ideas why it's happening?

Show NotifyIcon Context Menu and Control Its Position?

I'm trying to show a context menu when I left-click a NotifyIcon. Just calling NotifyIcon.ContextMenuStrip.Show() doesn't work very well. A solution has been posted here before that calls a secret method using Reflection:
Dim mi As System.Reflection.MethodInfo = GetType(NotifyIcon).GetMethod("ShowContextMenu", Reflection.BindingFlags.Instance Or Reflection.BindingFlags.NonPublic)
mi.Invoke(Icon, Nothing)
This works great, except that I also need to control where the menu is shown. I want to wait for the SystemInformation.DoubleClickTime to elapse between receiving the NotifyIcon.MouseUp event and displaying the menu, so that I can handle single-clicks and double-clicks separately. But invoking the ShowContextMenu method displays the menu at the current mouse position when ShowContextMenu is called, not when the icon was actually clicked. Which means that if the mouse moved during the DoubleClickTime, the menu will be displayed in a different part of the screen. So if I can control where the menu is shown, I can just save the mouse coordinates when I receive the MouseUp event, and then I can ensure that the menu is displayed near the icon. Is there a way to do this?
Thanks in advance.
Well, I just discovered that there are existing programs that exhibit this same behavior. I just went through all the icons in my system tray and about half of them do it. If you left-click the icon and then move the mouse during the delay before the menu appears, the menu will appear at the last mouse location, wherever that is on the screen. Snagit is one application that does this. Outlook is the only program in my tray that always shows the menu where I clicked the icon. But Snagit looks like it's using a .NET ContextMenuStrip, while Outlook is probably using a native menu.
So either this is standard behavior, or it's a problem that no one else has been able to solve either. And as a user, I've never noticed this behavior until yesterday when I was testing my own application. So I guess it's not that big of a deal and I won't worry about it.
