Hello All,
I have an application which I wrote in VB.NET.
The startup form is an MDI form. When I load any of the child forms, there
is a flicker in the left upper portion of the MDI form, in the shape of a
grey rectangle, until the child form loads and then it disappears.
Has anybody seen this? Is this a bug?

I've seen some weird things with Windows Forms on a computer with a GeForce
2 card. Updating to the latest drivers worked for me. I know what you mean
about the flicker.
Maybe your MDI form contains processing-expensive code that's run after you
do your Show()-call. Try to run all code necessary for the MDI child before
you call Show(). You might also want to try putting a MdiChild.Update() in
there to force the form to paint.
