Your use of BeginPaint()/EndPaint() is incorrect. You must call these ONLY during WM_PAINT. You cannot hold on to the hDC returned by BeginPaint() and use it for an indefinite amount of time.

If you need a device context outside the paint event, you can use GetDC() to get it.

Right now you're calling "BeginPaint()" everytime your window is sent a WM_PAINT command but you're only calling "EndPain()" when the window is destroyed, this doesn't add up. You should call "EndPaint()" at the end of your WM_PAINT condition.

Or something like "RedrawWindow()" might help: http://msdn.microsoft.com/en-us/library/dd162911(VS.85).aspx
