I wouldnt think so as the software for the softphone resides on the PC itself, and now our contact list is on a MJ server. I would THINK you should be able to go back and forth without a problem.
BUT this being MJ land ONE NEVER KNOWS and logic rarely comes into play
I use MJ primarily on a Win 7 machine at home, but when I take it to the lake house, I plug it into a XP machine and it works fine there and also when I return to my home.
