Win7 Pro - Welcome Screen w/ No User Account Showing...HELP

taken out of Sleep mode and my Win7 Pro Welcome Screen has No User Account Showing and nothing else to click on either. i could force the pc to shut down and restart it, which would no doubt fix this "glitch", but this is my biz computer and i have many dozens of client files open and some may not be fully saved. so doing a force restart would cost me a couple hours of work.

this is on a Fujitsu Tablet PC, but that should have no bearing. it is a convertible with touch screen (slate mode) and keyboard...no optical drive.

any ideas??


thanx!! :cool
