Silverlight copy dialog makes IE11 freeze - silverlight

We are having problem with a Silverlight 5 app and IE11.
Suddenly, it's no longer possible to copy-and-paste from a Silverlight application to the clipboard, after upgrading to IE11.
When the Silverlight dialog that asks you for the right to access the clip-board appears, then IE11 freezes. This behaviour has also been verified on IE11 och two different Win 8.1 computers.
We have also tried to add the site to trusted sites, and 'Allow programatic access to clipboard" to Enabled. But it dosnt help.
Any suggestions?
Anyone knowing if this is something Microsoft is addressing?

Ran into the same issue, running IE as administrator ended up clearing up the freezing issue.
From there you can then check the box to [remember my answer], click [yes] to allow clipboard access for this site, then restart IE (non-admin) and it won't freeze when accessing the clipboard.

"Error loading documents" in Firebase Database

I'm experiencing error when trying to access Database menu item within Firebase console.
It's a new Database with literally couple records of data but screen keep spinning for ages and then returns message "Error loading documents". In the same time I'm able to access Authentication menu item without any problem.
Note: I'm using MacBook Pro with Catalina 10.15.4 and Safari browser 13.1
It looks like it's a Firewall which is blocking my access to Database section within Firebase Console. Since I'm working on the corporate Mac I don't have control over it.
Workaround that works for me: use alternative private device ie. Mobile Phone.
Disabling the Add-Block fixed mine
For me, the problem was Safari. I was able to access the data programmatically but not via the web UI. Also, Safari worked well for the first few days I used it. I found that when I switched to Brave, I could see all my documents in the console.
On safari it doesn't work. I had to switch browser to Firefox!
Since last Firebase update it doesn't work on Safari anymore, don't know why I tried everything (Ad-block, firewall, ...). Even on mobile.
You have to use another browser to access your firestore docs...
April 16, 2021 : issue fixed, works again on Safari
I had the same problem and I was using windows Microsoft edge, I was using adblocker extension and I turned it off, but it didn't work. Then I opened the console on a chrome browser on a physical device and it worked!
I was trying to access the console in my work laptop with a vpn running in the background. Turn off that vpn and refresh console page. You should be able to see all your documents now.

How to tell if IE9 is forcing a page reload

Is there any circumstance that would cause IE9 to force an unrequested page reload? If so how can I tell that this is occurring? Is there a log I can look at or custom event I should be looking for in event viewer?
I am troubleshooting an issue with an AngularJS web application that only exists in IE9, it works fine in newer version of IE and works on FF, Safari, Chrome. When testing in IE9 I see no errors in the console but I am getting redirected to my applications login page. This redirection always happens on a page reload, hence why I think IE9 is forcing a page reload.
You can track navigation events, and the subsystems that invoke them, using the Network tool in Internet Explorer 9's F12 developer suite. Press F12, switch to the Network tab, and press "Start Capturing". From this point on, any further navigation events will be logged for your inspection.
Internet Explorer 9 uses an older version of the F12 developer tools, but you can still access the historical documentation for those on the Microsoft Developer Network.
The modern documentation for IE 11 is also available online, and much of what is shared about the Network tool in particular is still helpful even if you happen to be using Internet Explorer 9.

GetTempFileName not working in silverlight out-of-browser

I have a Silverlight application that runs out-of-browser. I was previously able to get the statement Path.GetTempFileName to work when I run out-of-browser but not when running locally. Now this is failing out-of-browser also.
I am getting this error
Message
File operation not permitted. Access to path '' is denied.
I am editing this because I have new information. I have another application which is very similar where I am not getting the problem. That is Path.GetTempFileName works fine. I cannot see any differences between the applications.
I need some hints as to what could be different between the two application. I am running both locally in debug.
Have you checked the Out of Browser settings in the Silverlight Project Properties page? There is a checkbox "Require elevated trust when running out of browser.
On the ShortCut not working. Try uninstalling the app from the Control panel and reinstalling. Then try it again.

Silverlight application crashes browser refresh

I just upgraded application to VS2012. Same SL5, just upgraded to async/await.
Everything seem to be working, but I can't restart application by refreshing browser. It goes white screen which I assume indication that it crashes. But how do I figure out why it is doing it?
EDIT: Very very stange. I just noticed if I click on address line in IE10 and hit enter - it refreshes just fine. If I hit refresh button (round arrow) - it goes blank.
I assume this is different "refresh types" in IE?!
It is a bug in IE and silverlight plugin
You can refere to this website: (https://connect.microsoft.com/VisualStudio/feedback/details/789004/ie10-shows-blank-page-upon-refreshing-silverlight-app)

How to test a Silverlight Application

I have a Silverlight 4 application, and I am wondering how can I see if my .xap file will cause or not a crash.
You will tell me that I can put it into a asp web server and launch Firefox but I would like to stay offline, just with a command line...
Do you have some idea ?
Thanks a lot !
I hope i was clear enought !
Set the application to run Out of Browser (OOB).
Right Click your project -> Properties -> Silverlight -> Check the box for Enable running application out of the browser and optionally change some of the settings for out of browser.
