This is probably a tough question to answer with out any code, but in case someone came across something similar to this in the past ill ask anyway.

i have a touch screen kiosk application that runs all the time on a computer. the user has no way to close it or open any other programs while it is running. but it seems like around 2 hours of inactivity, when you try to click something on the screen, the screen saver turns off(like it should) and the application doesnt draw itself back correctly. its all ghostly and such. but only after a long period of inactivity(like 2 hours or more) the wierd thing is that you can still press the windows key, and log off the computer and run other applications.

i know its tough to debug without any code but just wondering if anyone has had any freezing issues and what they possibly did to fix them?

thanks to anyone with any input, i appreciate it
