We've gotten a decent number of reviews in the app store saying we're crashing at startup, and while we do have some crash reports, none of them really stand out as a startup crash. We also didn't have anything we recognized as startup crashes reported in the beta.
If any of you get a startup crash with BaseCamp, please post or PM that crash log to me so I can try and nail down that crash for you :). The crash log text is generally accessible via a button in Apple's crash report dialog.
Please do report it also, I'd just like to be able to figure out which cases we already have relate to this startup crash.
