Question: What could happen for the hDC used by Worms to no show? It's non-zero for sure. How can I tell if it's valid?
There are probably a number of things that could go wrong there, but for a start you'll probably want to check where you're getting hWndPaint from, if that's a valid window, if it's visible, etc. Also, does this use ddraw?
