I have a mac running 10.2.1 and a PC running XP connected via a router. I set up a share on my PC, and then try to connect to it in OSX, except when I double click on the mounted share, the window starts to open, then disappears, and the share icon disappears too. it also appears to leave me logged into the share, just with no means of accessing it. this worked perfectly for me in 10.2.0. what's wrong?
