Comment 6 for bug 811401

For me, steps to produce this error were:

1. Clicked on logout indicator
2. Blank transparent menu appeared and panel got frozen
3. Blank transparent menu disappeared, but now the logout indicator does not respond when clicked on.

I am also having issues with the volume control, as mentioned above, but mine is different. It doesn't freeze when I use it, but it will only operate at 0 or 100%, nothing in between. Not sure if that is a separate issue or not, so I'll mention it anyway.
