well i tried that Function, but it didnt seem to have any effect. i went back to a previous build and i do not have the problem. the biggest difference is that the new build(the broken one) uses the backgroundworker and the old build(the one that doesnt freeze) uses System.Threading.

the background worker is created on Form1 which Form1 is the form that is the login form that will stay open for long periods of time and its the form keeps getting frozen. any ideas anyone??

RobDogg: i tried other apps too and the problem is not occurring so it is only occurring with the current build of the app, which is using the background worker..

thanks everyone
