Out of curiosity, at what point does it usually crash? Is it mostly after performing a certain action, or while AIs are taking their turns? Are you playing succession games with other people and opening the history log (ctrl-tab).
There was an old crash to desktop issue using SimCutie's extra colors. We removed that file back in April or so when we found the problem, and AFAIK there shouldn't be any reason for BUG to CTD anymore. But if there is, I'd really like to fix it!
Any information you can provide would help. Thanks!
