I am a real noob at Linux, infact Mint 12 is my first real try at using it and so far I'm loving it.
But a few minutes ago I came to this problem;
From System Settings > Universal Access I changed the text size from normal to small and then back again and I got an error; I don't recall what it said and I feel so stupid about it, but from then on my open windows just don't show in the bottom pane of the screen.
Even right-clicking the pane does nothing (I'll attach an image to make it clearer)

(As you can see from the image I have 2 windows open, yet they don't appear in the bottom. I can reach them with Alt+Tab but it gets annoying..)
Please help me, I've got no clue!
PS: Restarting the system didn't work
