I like this new little piece of software a lot, but this morning I encountered a serious bug in the Scapple-test-version that completely erased all my notes and left me with a empty scapple-file. I couldn’t undo or step back. I didn’t do anything special, either, was just editing a story-format. So it’s hard to help you with additional information at this point. Please be aware of this and good luck with the software.
