I had my Mac Pro under my desk and I was having trouble keeping a solid connection to my wireless Magic Mouse. I like using the Magic Mouse because I want to have the ability to scroll horizontally in my FCP and AE timelines. I've now moved my Mac, PC and external RAID behind my desk in a corner to isolate the sound for audio recording, so I get no connection to the mouse at all. Is there a bluetooth extender for the Mac? I could get the wired mouse, but I don't like having to clean the track ball on the Mighty Mouse every day to keep it operational.
