+Summary: DrawReversible Stuff Still Buggy
+
+Description of Problem:
+
+DrawReversibleLine, Frame, FillReversibleRectangle, etc don't draw
+correctly when the draw is in an embedded control (I think).
+
+
+Steps to reproduce the problem:
+1. Create a userControl, with a mouseMove event that draws lines
+2. Put that control in a Form Container.
+3. Move Mouse in control to trigger event.
+
+OR
+
+1. Compile attached test case with:
+mcs -r:System.Windows.Forms -r:System.Drawing -r:System.Data Form1.cs
+XORControl.cs
+
+2. Run the test case
+mono Form1.exe
+
+3. No reversible line drawing is done at all.
+
+
+Actual Results:
+No reversible lines appear anywhere.
+
+Expected Results:
+Reversible lines should appear. Coordinates of the mouse in each control
+should be calculated to screen coordinates, and a crosshair of size 10
+should be drawn using DrawReversibleLine(). These crosshairs should be
+drawn on every other control if the checkbox is checked. If it's not
+checked, it only draws on the control the mouse is in. The clear button
+just sends an invalidate message.
+
+How often does this happen?
+always
+
+Additional Information:
+Could it be that Mono is sending extra invalidates on child controls,
+causing the drawn lines to be overwritten immediately? The DrawReversible
+functions definately *are* getting called after examining the results of
+the --trace option. Ill attach a snipped output of that too.
+
+Eric
