KNode has no @#*%^! backup!

I had been working on a usenet message for about 20 hours. I was trying to reply to a question about ancient Germanic tribes living in the south of France during the rise of Charles Martel. I had been saving the message to draft with the reasonable expectation that it would be backed up. I opened the file to edit and while it was opened the power went out. The file is no longer in drafts, and KNode has no backup that I know of. I have two questions in this regard: 1) Is there a way to fish this file out of some kind of temp file generated by KNode? 2) Is there a tool which is as easy to use as KNode and which will backup my currently open files? TIA, Steven
