-Summary: Graphics: DrawString doesn't the string if a call to FillRectangle is next.
+Summary: Refresh problem during a Thread.Sleep
 
 This is a small sample from a Windows.Forms book, which shows a button, 
 and when clicked, a text appears for a fraction of a second. This example 
 calls Form.CreateGraphics (), Graphics.DrawString () and 
 Graphics.FillRectangle.

 I'm sorry, but I'm having some connection problems with my internet
 service provider, and right now I can't post any text with more than
 30 lines to bugzilla (this should change as I'm going to change of
 provider).

+It seems to be a SWF refresh problem as this code (changing
+button.Text) provoke an update and works as expected. 
+
+Updated Summary and moved back to MWF.
