+TargetMilestone: ---
+Summary: Form: windows is three times too big when opaque/transparent(?)
+Repro is ./ch02_Forms/OpacitySample and ./ch02_Forms/TransparencySample 
+from the sample code for the book "Windows Forms 2.0 Programming," by 
+Chris Sells and Michael Weinhardt, sources available from 
+Each tested on SVN head on Win32, 1.2.5_5 Win32 and 1.2.5_5 Suse VM.
+The first sample displays a partially transparent window, and the second 
+sample display an ellipsoid-shaped window.  Both are two to three times 
+bigger than expected (as seen in MSFT and in forms designer in VS).
+The first sample is meant to go transparent when unfocused (Deactivated) 
+and on focus (Activated) grow more opaque step-by-step.  The 'activated' 
+action does not occur on Win32 it appears that the timer does not run.  
+On Suse VM the timer does run (but -- I presume due to the VM -- neither 
+of the windows appear transparent).
+(The second sample's windows is meant to move when I/J/K/L is pressed.  
+On Suse VM it won't move to the right it just jiggles back and forth.  
+Don't know whether again this is an artifact of the VM).
