What the hell??

I'm typing along...feeling pretty good about the quality of my stuff...when suddenly it's like the backspace on my keyboard is stuck.  Over 200 words were deleted by the time I just closed out of Scrivener and restarted my tablet.  I still don't know what happened, but I suspect it was just a random, very poorly-timed glitch in the tablet.  I couldn't get the on screen keyboard to open at all, no matter what program I was in.  So I had a pretty ridiculous delay tonight in my writing, but it woke me up so I was still able to recover (rewrite) the jist of what I had down originally and reached my daily word goal.  But seriously...what the shit?  I couldn't be more annoyed...
