Unfortunately after spending a significant amount of time on a topic (Responsive HTML5 format) I seem to have lost all the content. I put my computer in standby mode, but later restarted it, and I can only assume I hadn't saved the file in question. So frustrating.
Is there a location for temp files that I might be able to recover from? And for future reference, is there an autosave feature that I can set to save all unsaved files every so many minutes?
