Comment 48 for bug 923749

It is 2012-04-28 and this bug still exists. I have a geforce 9800 gtk+ but using the old "ubuntu approved" drivers supplied as "recommended." There will be a slight black shadow on the left when I want it to appear, but it doesn't open and the black "glow" collapses. It takes repeated attempts of bouncing the cursor to make it appear after it is stuck. I'm using Beta2 and I haven't been offered the final release in System Update yet.
