Scrolling in Fence groups stops working.
Every few days I find that the the scrolling stops working inside the fence groups. Restarting the computer fixes the problem. In messing around with it today, I discovered that if I drag the fence, the scroll bar and icons remain where they were on the desktop, though they become invisible. I can slide the fence window back over to reveal them, like a magic window to the icon dimension, or something.
I've also found that if I change the desktop resolution, everything refreshes and starts working again.
My Google-Fu was to weak to find a solution, any ideas?
