+Summary: Regression in MDI drawing.
+Description of Problem:
+There seems to be a regression issue when drawing a second MDI window with
+controls on top of an already present MDI window.  The controls aren't
+redrawing well at all.  Once one of the drawing issues happens, moving the
+new MDI window around never removes the drawing of where the window was before.
+It happened using custom controls at first, and I can't reproduce that with
+a test case.  However, I found pretty much the same thing happening with
+DataGrid control drawing and have a test case attached to that.  I think
+they could all stem from the same issue.
+Steps to reproduce the problem:
+1. Compile and run attached test case.
+mcs -r:System.Windows.Forms -r:System.Drawing -r:System.Data
+-out:MDIThingy.exe *.cs
+mono MDIThingy.exe
+2. Click on the button "First" to generate the first MDI window.  Click on
+"Second" to generate the next window with the DataGrid.
+3. Follow the instructions.  Mouse over the row headers.  Then drag the MDI
+window around.
+Actual Results:
+Drawing doesn't seem to refresh right.  Scroll bars keep moving down and to
+the right, not entirely refreshing what's being drawn.  Window (when moved)
+looks like it's getting copied and pasted all over the place.
+Expected Results:
+DataGrid window works properly.  
+How often does this happen? 
+All the time.
+Additional Information:
+First noticed a few days ago.  Tested this morning, SVN version 74410 and
+still present.
