Form flicker

Hi,

I am writing an application that uses forms as modal dialogs.

So the Main form has some code like

form2.ShowDialog();

Once the dialog has been used it will be calling the this.Hide() on the on close event.

This causes form1 to show a very annoying flicker even though double buffering is enabled on it.

Is there any form property or style I am missing to avoid this flickering

Thanks a lot for your help
