>I have a C# windows form that when you click one of the buttons, it starts another process and waits for it to finish. It works fine. BUT when the process finishes, my form is displayed for a second or two or three, it looks funky! The buttons and other controls are not there and there is leftover crud from the finished process displayed in their place and it just doesn't look professional. Is there a way to avoid this problem or can I hide or minimize the form while the process is runnning and restore it when the process finishes? thanks in advance! Dave

Dave,

It might be better to use a loop and WaitForExit(250) to allow the window to respond to paint events. It might also help to Invalidate the window immediately after the loop terminates.
