+Summary: Transparent Control created with CreateParams ExStyle of 0x20 does not correctly draw as a transparent control.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+A control that is created to be transparent is not actually functioning as
+  intended. The control appears transparent until the control that it
+covers updates. The transparent control remains the previous color of the
+control that it covered.
+
+
+Steps to reproduce the problem:
+1. Compile the example code.
+2. Run example code.
+
+Actual Results:
+Run compiled application on mono, clicking on the lower half to the
+blue/orange control will toggle the entire control's color to be either
+blue or orange. The top portion of the control is covered by the
+transparent control and remains orange.
+
+Expected Results:
+Run compiled application on windows, clicking on the lower half to the
+blue/gray control will toggle the entire control's color to be either blue
+or gray. The top portion of the control is covered by the transparent
+control. The covered area of the colored control will change color and the
+transparent control will change.
+
+How often does this happen? 
+Every time.
