Main form doesn't repaint until mouse moved

I've got a c# desktop app with various menu items that display modal dialogs
for changing app settings, etc.. Standard stuff.

After a particular dialog is closed, the main form doesn't repaint the area
that was covered by the child form until the user moves the mouse.

I can't see how this one form is different from the others, or what I may
have done to prevent the main form from repainting. Any suggestions on things
to check would be appreciated.
 
Hmm, seems the main form isn't really active (keyboard is not active), until
the mouse moves.

I have a similar problem with a 3rd party control. After i close a
Dialog (MessageBox), it didnt repaint the control properly. To fix
the problem i called the refresh method of the control.
I think this could be a .net problem where it thinks it does not need
a repaint after a dialog is closed.
 
I found that the symptoms are not 100% consistant. Sometimes the main form
repaints just fine. But I also ended up having to do a refresh in the main
form after the child dialog closed.

I am certainly open to someone proving me wrong, but it sure seems like a
bug in the .net framework.
