Since Windows 10 creator update, we have a touch compliant WPF App that crashes:
Crash occurs when we are moving from one window to another on a touch action.
Here is the revelant part of the stack :

Let me be precise, the product is perfectly working on windows 7/8/8.1/10(non creator) and we do not use any Wacom or stylus device except our finger :)
If you have any idea, let me know and i will test it.

I've encountered a strange issue regarding the GridViewPinButton visibility in RadGridView.
My only wish is to disable this functionality- to set the GridViewPinButton visibility to collapse in every row in RadGridView.
Now, I have one place where it works great and another one where I can see this button while I'm hovering the rows.
In both places I haven't written any code concerning the GridViewPinButton , and in both cases the visibility of the button is set to collapsed by default.
The only difference I can see is in snoop :
When it works well, GridViewPinButton does not have any child elements:
while it has them in the second case (where it does not work well):
When I click the button, I get the error:
Could not find any resources appropriate for the specified culture or the neutral culture. Make sure Telerik.Windows.Controls.GridView.Strings.resources was correctly embedded or linked into assembly Telerik.Windows.Controls.GridView at compile time, or that all the satellite assemblies required are loadable and fully signed.

I'm getting some very odd behaviour with a WPF window that I am able to recreate with a basic application. When I minimize my window from a maximized state, then restore my window it does not return maximized. I've implemented code to try and counter this, but the window still returns to a WindowState.Normal.
An important thing to note about this is the this only happen when I am running the application stand-alone. If I run in debug mode in visual studio everything works as expected. Also, this behaviour occurs on multiple boxes, not just my own.
Steps to reproduce with code below:
double-click WpfApplication1.exe
ensure application is maximized
click the minimize button in the top right
click the application in the taskbar
Expected Result: application window returns to a maximized state
Actual Result: application window is in restored state, with WindowState = WindowState.Normal
Here is the XAML code for the demo window.
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525"
WindowState="Maximized"
Activated="MainWindow_OnActivated"
StateChanged="MainWindow_OnStateChanged">
<Grid>
</Grid>
</Window>
and the code-behind:
public partial class MainWindow : Window
{
private WindowState _lastWindowState;
private bool _activating;
public MainWindow()
{
InitializeComponent();
_lastWindowState = WindowState.Normal;
}
private void MainWindow_OnActivated(object sender, EventArgs e)
{
if (WindowState == WindowState.Minimized)
{
WindowState = _lastWindowState;
}
}
private void MainWindow_OnStateChanged(object sender, EventArgs e)
{
if (WindowState != WindowState.Minimized)
{
_lastWindowState = WindowState;
}
}
}
In my real application I placed logging code before and after the WindowState set in the OnActivated function and in the StateChanged function. When activating from minimized I get the following:
OnActivated 1 - _lastWindowState: Maximized
OnStateChanged - _lastWindowState: Maximized
OnActivated 2 - _lastWindowState: Maximized
OnStateChanged - _lastWindowState: Normal
Finally, in case this helps, this is the Environment.StackTrace in the last StateChanged call that happens:

We are running .NET 4 with Visual Studio 2012 and this is a WPF application.
The wired thing is if I do not pass parameters to the sql query, it works fine. Once the query has some parameters, the error occurs.
In Visual Studio, the platform is set to AnyCPU which is what we want. We do not want to change this to x86.
Thanks for the help.

Has anybody ever had similar problems with MFC/WPF in 64bit ?
