Cataclysm is rude (in the software sense). It steals focus, even from the task manager in win7. I got perma-paralyzed by the Amigara Horrors and ended up having to reboot since they couldn’t get through my armour to kill me. Alt-tab wouldn’t work since Cataclysm kept stealing back focus and alt-f4 did nothing. I could ctrl-alt-delete out, but trying to bring up the task manager to shut down Cataclysm resulted in Cataclysm stealing focus again instantly. I waited about ten minutes for my character to starve to death, then ended up having to ctrl-alt-delete and reboot. 0.C stable, tiles, win7-64.
