[DM-MUG] Floating Expose button

[Chris Tyrrell]

Here's something I can't figure out. I restarted my iBook G4 yesterday 
after the sound output stopped working. I normally put it to sleep when 
I'm done with it, so it hasn't been restarted in quite some time. After 
rebooting, the sound was back, but I now have a new feature - a 
floating Expose button. It's round, blue, translucent when the mouse 
isn't over it, and floats above everything else. Clicking on it does an 
Expose F10. Option-Clicking does an F9.

Where the heck did this thing come from? I kinda like it, but it bugs 
me that it just appeared.


Thanks,
Chris
