Hi all, got myself a copy of Quake, the one that installs the WinQuake port), and while the dos version runs, it runs too fast, so I use the WinQuake port instead, which is absolutely perfect ..... bar one thing.

When quitting the game, I will get a black screen. Either completely black, or sometimes with a dos type flashing line, sometimes with some corruption all over the screen. No response from keyboard either, so I have to hit the reset switch.

Any ideas why this happens?
