 			// Dispose (causes crash on Mono)
+------- Additional Comments From peter at novonyx.com  2005-12-20 13:47 -------
+The sample is broken. NEVER dispose the graphics context in a paint 
+event handler, you didn't create the Graphics object therefore you 
+shouldn't dispose of it. You might need to call the base class and it 
+can't do it's job with a disposed graphics object. However, I did fix 
+the resulting crash in System.Drawing. If you update to svn head it 
+will no longer crash
