First, we're not on the Mac codepath any more, we're using SDL, which 
handles the input, and was modelled on the Linux/X11 code...I remember 
there being some discussion about the mouse sensitivity in 
there...anyone remember the details?

It's a PowerPC issue, not a Mac one...it doesn't happen on Intel Macs, 
but it does on PowerPC Linux. We really need to figure out what's 
happening there. If you want to tackle something, this would be really 
appreciated!

Not intentional, but probably a casualty of tossing the Mac-specific 
code. code/unix/glimp_sdl.c can probably catch that key combination and 
change to windowed mode, but I'd be inclined to avoid that...some 
jackass will have Command set up to strafe and tab set up to change 
weapons.  :)
