Saving Projects to Network Share

I've had this problem with both VS 2010 and Visual Web Developer 2010. I want to save my projects on a network share (which I have as a mapped drive), because our network drives are backed up daily.

For some reason though, VS only shows local drives when I try to save a project - all my network drives do not show up.

Is there a way around this somehow? Why does it behave this way?

SOLVED

It doesn't show my mapped drive letters but if I go through "Network Places" I can browse from there.
