I want to start off by saying I have never had any problems with Zandronum before the 3.1 update.
Here's what normal: Double click the Zandronum icon, a window appears, code scrolls, screen goes black, then the Doom screen appears. Play as normal.
Now this: Double click, get the window, code scrolls, screen goes black, then game crashes and this appears:
At this point, my computer freezes and I have to hit the reset button.
Ideas?
