I'm running Win 7 on a 2010 MacPro under Bootcamp. I have a classic IBM Spacesaver II keyboard (PS/2 connection) plugged in via a USB adaptor.

I've been running this set-up since I got my first MacPro back in 2007. This year I've started experiencing an issue (possibly related to Lion?) which involves the Windows Control key.

Although the key isn't physically down on the keyboard, Windows thinks it is so for example pressing A invokes Select All and turning the scroll wheel on my mouse makes text get bigger and smaller.

Sometimes unplugging the keyboard for a bit fixes it, sometimes a restart is required. Swapping the IBM keyboard for the nasty standard modern 'calculator' keyboard one gets from Apple nowadays doesn't have any effect. It is as if something is toggled on and can't be toggled off.

This is starting to drive me mad and is affecting my work, the Apple keyboard won't map to the Windows one as I'd like (e.g. => Win (windows key) and pops up the Start menu).

Do you know why this is happening and/or if it is fixable?

This question came from our site for power users of Apple hardware and software.

Just because this is taking place on a Mac Pro doesn't really make this an Ask Different question. It's either an IBM hardware question, or a Windows question (accessibility -> sticky keys, maybe?). – VxJasonxV Jan 5 '12 at 11:04
The same keyboard doesn't cause any problems when connected to a Windows XP/7 box ... – 5arx Jan 5 '12 at 12:29
What happens with the same hardware when booted into OSX? – George Pearce Jan 5 '12 at 12:41
Haven't tried that yet - got code to write :-( Will try shortly and post the result. – 5arx Jan 5 '12 at 14:03
The same keyboard doesn't cause any problem when not connected to your Bootcamp'ed box. Just because it doesn't happen on another Windows computer does not make it a Mac Pro problem. Not to mention, per my suggestion, that doesn't rule out a software (e.g. Sticky Keys) problem either. Basically you changed everything and it worked, but that really didn't narrow the problem down. – VxJasonxV Jan 5 '12 at 16:18
