F***ING AUTOCAD

So this morning I show up to work.  Strangely, my computer is at the "Login" screen.... wierd, I left AutoCAD on last night.  It can't possibly be on the login screen!  Nope, sure enough, someone restarted my computer.  Ok, that's not a huge problem.... I fire up AutoCAD, and go to my last worked on file, the cross section, elevation and detail of a huge timber awning for a building in Squamish.

Huh.  All the work I did yesterday is gone.  Peculiar. Apparently, it didn't save when I hit "Save" last night.  No problem, we have auto-backups for that occaision.

Huh.  My temp directory is empty.  Absolutely auto-backups. 

Huh.

Three hours of work, gone, because someone flicked off my computer without thinking "Hmm, this isn'y my computer, maybe I shouldn't do this."

FUCK.
