What is causing Labwindows to lock-up occasionaly, but when the mouse cursor is moved the program starts scanning again. I am using two graphs and some asynchronous timers.

This seems to be realted to the mouse, as I have been able to recreate this by left clicking many times on an indicator field. But I have to try very hard to recreate this. Is there another reason that causes this?

Hi,

When you say "lock-up", do you mean that the application seems to pause by not updating the user interface? It sounds almost like either a callback is taking a long period of time before returning control to the application or possibly another application is using up processing time. I would try to isolate the issue by stopping all other applications and then taking out parts of the UI piece by piece to see where the hangup may be occurring. Let me know what you find! Thanks!
