Well, I have advanced a bit this weekend. I noticed that one of my
test app does indeed show this regression after the patch we are talking
about.

As the case is a lot more simple than the one I was trying to debug 
before for this problem, I have been able to understand better what
is happening. The problem shows itself in the following case :

- invalidating a window
- hiding it
- deleting it

and after that the paint count is > 0.

I can make the paint count change correctly with the following change :

+++ winpos.c    Mon Nov 12 09:47:08 2001

if (!(winpos->flags & SWP_SHOWWINDOW) && (winpos->flags &
SWP_HIDEWINDOW))
         {
-            WIN_SetStyle( winpos->hwnd, wndPtr->dwStyle & ~WS_VISIBLE );
             /* clear the update region */
-//            RedrawWindow( winpos->hwnd, NULL, 0, RDW_VALIDATE | RDW_NOFRAME |
-//                          RDW_NOERASE | RDW_NOINTERNALPAINT |
RDW_ALLCHILDREN );
+            RedrawWindow( winpos->hwnd, NULL, 0, RDW_VALIDATE | RDW_NOFRAME |
+                          RDW_NOERASE | RDW_NOINTERNALPAINT |
RDW_ALLCHILDREN );
+            WIN_SetStyle( winpos->hwnd, wndPtr->dwStyle & ~WS_VISIBLE );
         }
         else if ((wndPtr->dwStyle & WS_VISIBLE) &&
                  !IsRectEmpty( &oldWindowRect ) && IsRectEmpty(
&newWindowRect ))

Now, I don't know why this RedrawWindow call was commented out :-/

That patch fixes the hangs I was having. Thanks a lot. I think you should
submit it.
