If this is in the wrong place, please move it.
This problem has been constant recently, and it only seems to happen when I go AFK for a period of time (maybe when my screensaver comes up)
And my toolbar/taskbar completely disappears and is basically not there. If I right click in that area it's like I'm clicking on my desktop. But my start button is still there.
To bring it back I usually have to log off, but it's annoying.
Here's a screenshot.
