If you're using Logic Pro or Logic Express 7.1 and use a Scandinavian keyboard layout, you may notice that Logic key commands that incorporate modifier keys (Command, Option, and so on) do not work as expected after upgrading the computer to Mac OS X 10.4 "Tiger."
As a workaround, set the commands using the "Learn by Key Position" button instead of the "Learn by Key Label" button in the Key Commands window in Logic.
This document will be updated as more information becomes available.
