it crashes after the cutscene.

I'm having the same issue. I'm playing the last campaign with Zahir, and I decided to patch to version 1.6 to get the new features, but now my mouse cursor sometimes glitches, and the game inevitably crashes to the system after any mission ending. I specifically tested it on early saves, and it's the same – it summarizes the results and crashes! Plus, there's some kind of glitch with the fonts; they're not proportional. It's possible that the fonts in the patch are overlapping with my existing fonts, which are in TT format, causing the glitch. Can anyone suggest what to do?
P.S. Before this, I had version 1.41 installed, and it worked perfectly.
