Description Colin Harrison 2006-06-05 07:06:21 UTC 
Sometimes (every blue moon!) repeated painting of the contents of the clipboard 
into an X Window can occur in Xming (same code as Cygwin/X).

The WM_DRAWCLIPBOARD code calls SendMessage() before processing clipboard 
change. Since the SendMessage() function does not return until the receiving 
window has processed the message it's not surprising things can go wrong. The 
attached path reverses this code order in WM_DRAWCLIPBOARD and if nesting is 
detected makes a better stab at correction.

The patch applies to both the monolithic and modular cygwin trees.
