Scapple crashing on Mavericks

Scapple 1.1 on Mavericks has been crashing when I try to copy or save to a new file format. Why and what can do about it? Cheers.

There aren’t any known crashing bugs at this time, which isn’t to say you didn’t find one, but first check the more common cases for crashing in Mac software: reset your preferences, reinstall the software, and make sure all third-party utilities, plug-ins, contextual menu items, services and so forth are up to date and rated for you OS X version. (You can check for the latter by performing a safe boot and seeing if Scapple continues to crash with all third-party software disabled.)
