Skitch started doing the SAME thing for me today. UGH. I even tried restoring from backup. I could annotate yesterday, today, I couldn't because it crashes after I try to sync--very strange. I didn't update my Mac until AFTER Skitch stopped working (as a way to hopefully resolve the issue). Anyone have a fix yet? I love Skitch. **Also, any idea why we can't find it in the Mac App Store?
