We're at a loss here. We have a large VB6 app that has worked flawlessly for years in XP. We are now trying to run it on Windows 7. It works fine, but the VB timers randomly pause for a while and then restart by themselves. We have 4-8 timers in an app (multiple apps). The timers have different intervals, anywhere from 100 to 750. We log when we enter each timer and when it exits. They always enter and exit, but randomly, a timer (usually the same one) will not trigger for anywhere from 8 to 30 seconds later, once in a great while even longer. We have tried writing a simpler app with timers to reproduce the problem but have been unsucessful.

Any suggestions for where to look? has anyone heard of anyhting like this? We're suspecting something has changed in Win 7 because it has always worked with XP.
