I just upgraded to 10.04 and almost everything worked but ...

I can't type the "S" key anymore. It doesn't matter where I am, in a terminal, in Firefox, anywhere I type "S" the system menu in the top right corner of the screen drops down and I'm no longer in the window I was originally typing in.

Note, I'm VNCed to the machine. If I use the machine directly or through a remote shell, no problem but if I'm VNCed, which is how I normally access the machine, then I get this "S" problem.

Also, I'm VNCed to it's own desktop. Meaning I'm not sharing the main desktop.

Any ideas how to fix this? I'm not sure even where to start looking.
