This is a problem I've noticed on two Macs I currently own. First I had my 20" iMac with Vista installed, and currently I have a 24" iMac with XP installed. In both cases, when I'm in Windows and need to restart (for whatever reason) and want to go back into Windows instead of OS X, the Option key does not function correctly to bring up the OS select screen, and instead will go straight to OS X, as that is the default OS I have set up to boot into. So basically, if I restart from OS X, the Option key works fine and I can choose to go into Windows, but restart from Windows and I have no choice in the matter, it makes me go into OS X. Any idea why? My first thought is that it has to do with the fact that I'm using Apple's bluetooth keyboard (and mouse), but once the computer has actually restarted, why would it matter? Does the computer remember the BIOS from Windows when it restarts, and therefore fails to recognize my bluetooth? For the record I have to turn my keyboard off then on again when entering windows to get it to be recognized and work, but not the mouse, which works fine. Suggestions?
