iTunes 7.6 installed on an mpb (leo) and 7.6 on Vista Ultimate x64. iPhone 1.1.2 Jailbroken and all.

iPhone/itunes wants to sync on both, even though previous 7.5 version allowed me to pick and choose what sections I wanted to sync on one computer and on the other.
ie:

on MBP I would sync my music, movies, tv, podcasts.
on Windows I would sync my contacts and pictures.

This is now not possible anymore for some reason.
Both wants to sync whatever I have choosen on the iPhone and the mbp.
So now I can't sync my photos unless my iphone looses those (at least thats what itunes says) with my win box.

Anyone else experiencing this issue?
