Mac users: do you know whether the C5 beta overwrites your C4 preferences file, or does it make one of its own? I'd like to try the beta, but I'm wary of corrupting my existing prefs file. The C4 prefs file is at ~/Library/Preferences/Carrara.plist. If you change your C5 prefs and the modification date of that file changes, then I guess that's the answer. Thanks, Joe
