+        
+        Mouse hover does not work as expected with the flash in some sites.
+        - http://www.bbc.co.uk/ Hover over the map
+        - http://www.barbie.com/ Hover over the menu items (Games, Videos)
+        The problem appears to be that Flash queries NPNVnetscapeWindow on every
+        mouse hover. I do not how flash uses this value but returning 0 when flash
+        is in windowless mode solves the problem (When using QGraphicsWebView we
+        inject wmode opaque, thereby putting the plugin in windowless mode).
