--- Comment #3 from Nikolay Sivov bunglehead@gmail.com 2011-08-19 01:13:52 CDT --- It's not necessary user32 problem, there's no such thing as double buffer painting in user32, it's done entirely in Delphi component. That's why I always ask to use Lazarus for such simple test application, in case a problem is visible with it too so I can dig into its LCL sources.
