Transparency and repaint

[Rene]

Hi,

I have a form with a transparency color white and some picture as background
on this form where the corners and border of this picture is white to create
some skinned form.

When this form is repainted (dragging another window over the form) the
white/transparent parts are not correctly updated but shows rubble (like a
form/application without processing messages).

Is this a software issue, is there some (repoaint) property to set or is it
hardware (vga)?

TIA,

Rene

I tried to duplicate your problem and couldn't. You might try setting the
background color of the form to white even though you are using an image
overlay. I am assuming you are not painting the background image in onPaint,
but are using the background image property of the form. . Can you post some
code excerpts and the properties you are setting on the form?

I've created some similar controls and what I do is create a GraphicsPath
around the perimeter of the control with rounded edges, then I set the
control's Region using the GraphicsPath. Take a look at
