I have just got myself the SqueezeBox Boom and first I installed SqueezeCenter on my XP machine and had no problem to browse for the network share (mapped drive) where the music is and set that as being the musicfolder.
Later I installed SqueezCenter on my Vista machine and now I cannot browse anything outside the local machine - only the local drives. I have no problem using the network shares when doing other work.

Any solution to this problem??
