Apparently Adium caches my MSN list locally, and any time I make changes to my list with my Windows client they get reversed as soon as I sign in with Adium. For example, if Contact A is in Group 1 and move them into Group 2 in Windows, then when I sign on with Adium and go back to Windows they will now be in both Group 1 and Group 2.
How do I go about deleting the copy Aduim has cached without blowing away all of my other preferences as well?
