zoombrowser XP shared docs

[ourgeoff]

I'd like to register an image folder in my 'shared documents' folder under XP, so that I can access it from any computer on my home network. Problem is that the 'register image folder' window shows my C drive but for some reason does not show the 'shared documents' folder - as if it were not there?
Any suggestions? I'm on zoombrowser ex 3.1.0.40
