WPF application loses touch capability

Question

I am developing a WPF application (.NET Framework 4.5) and I have a strange behavior.

The application is meant to run on a Windows 8.0 with a Elo Touch screen (elotouch.com).

When running the application in Release mode, on the production machine, the application randomly stop accepting touch events.

The application did not froze (it's still actionnable with a mouse), and the other applications and the system still respond to touch events.

Any idea where this issue could come from ? Windows ? The Framework ? My code ?

Edit : Reducing the screen resolution fixes it, but I'd rather have my application running in high resolution

Answer 1

Upgrading to Windows 8.1 fixes the problem. It's a constraining solution but it seems to work for people with this issue.
