This seems to be completely random. The only correlation is that so far, it has only happened either when I tried to go into a city, or tried to change the production of a city. It happens fairly rarely, but is still enough to be annoying. It just closes completely, with absolutely no warning whatsoever. It just happens in the blink of an eye: one second I'm clicking, the next I'm looking at my web browser. There isn't even one of those stupid little "send info to microsoft" popups you usually get when something crashes. I have 1.29f with the DyP mod over it, so I don't know if it's a problem with the patch or the mod, or something else. Has anyone else ever experienced this?
