Hi

I have written an application that runs in a window about a quarter of the size of the screen. If I have another window open on the screen at the same time and then drag that program across my application it looks like everything in my application gets wiped from the screen, once I stop moving the program acrros the screen my application redraws it's self. This does not seem to happen with any other window programs that I Have tried it with just mine. Is there anyway i can stop this from happening as it does not look very good

thanks

Simon

What is your application doing at this time as the white screen sounds like the CPU is maxed out or the main thread is too busy to refresh the form

It shouldn't be doing anything.
