Zandronum crash.

[DeCaff2007]

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?
