Yeah convincing a company who has been using the whole MS visual studio suite for 10 years to totally abandon their development/version control system is not an easy task, if possible at all. I posted this a while ago and have since just resorted to using the PC i have next to me to use Sourcesafe and then swapping the file myself between these two machines. I'll eventually get Virtual PC but the thought of it makes my stomach turn. I'd like to find a way around it.
At least I've been given the go ahead to use OS X as a development platform, that's half the battle right?
