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

  • have you found any workarounds for this ? I've got a similar scenario were in high resolution touch works badly. but only when the visual tree is very large. – eran otzap Jul 02 '15 at 13:59
  • @eranotzap Upgrading to Windows 8.1 fixed the problem for me – skwi Jul 02 '15 at 21:15
  • wow that's a useful piece of info, 10x . – eran otzap Jul 03 '15 at 06:39
  • I'm sorry that my answer doesn't suit your need, but you asked me if I've found a workaround for a problem I had last year. I did not say that I have a solution for your particular issue, just how mine got solved. – skwi Jul 03 '15 at 11:26
  • I'm sorry i didn't mean to sound cynical. it really is helpfull. I got one system with windows 7 and one with windows 8 . – eran otzap Jul 03 '15 at 12:00
  • My bad, I'm glad I could help then :) – skwi Jul 03 '15 at 20:29
  • lol after reading my comment again it does sound rather stingful – eran otzap Jul 04 '15 at 16:48
  • in your situation did this behavior occur only if the visual tree was very large ? – eran otzap Jul 04 '15 at 16:49
  • I don't remember well the details as this was a project that is now a year old, but it was, graphically speaking, quite a simple application so I don't think the visual tree was very large. – skwi Jul 05 '15 at 20:14

    Having very similar problems. Anyone find a solution? For whatever reason the Manipulation events are no longer being called, it goes into this mode randomly. – Chris Zeh Jul 02 '18 at 19:35

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