"lock desktop" issue

[eddski]

I'm using natty and when I go to lock the desktop(using the lock session icon on the taskbar)I can't get back to my desktop, i am literally locked out. All that shows is a black screen. I can tell its on, but ctrl alt del, rt mouse clicks, and every button on the keyboard pressed and nothing happens. I have to hit the reset button to reboot. thanks in advance.

Things like that are usually video driver issues or have been resolved long ago.

Is the system fully updated?

updated a couple days ago, but i've never had this problem in the past, with this laptop nor any of the desktops.
