In this setup, i had a mix of normal pc’s and a bunch of new mac (airbooks) which ran both snow leopard and Windows 7.
It started out with the some users complaining about their danish published office applications switched to using US keyboard layout
and naturally i started testing (logged on with same user account) and found no issues at all. We tested a bit, playing around with the language bar
and the local region settings, and we found out that on the airbooks, on windows 7, it had 2 keyboard layouts installed (da-dk, and danish-apple)
