Created an attachment (id=204863)
 --> (https://bugzilla.novell.com/attachment.cgi?id=204863)
example: ToolBarUserPaint.cs

Description of Problem:
I have a derivative of ToolBar in which I set UserPaint and
SupportsTransparentBackColor to true (using SetStyle) so that I can have a
ToolBar with transparent background and draw my own buttons on it.
this works fine on Microsoft.Net but not on Mono 

Steps to reproduce the problem:
1. compile the example thus:
mcs -r:System.Windows.Forms,System.Drawing ToolBarUserPaint.cs

2. run it and have a butcher's


Actual Results:
the toolbar background and buttons remain drawn by mono
with my circles drawn on top of them


Expected Results:
the toolbar should be transparent and only have the circles drawn on it

How often does this happen? 
every time with Mono
