Every time I add a screenshot to Skitch to annotate it, I get a message saying that I've reached my monthly quota. The problem is that I haven't (I've only used about 50kb), but I've received this message EVERY time I used it for many, many months now. It's really frustrating. "The sync operation cannot complete because you have reached your monthly quota..." I have sync set up to manual, never sync, and don't save the image once I've added it to an email.
