Running Windows XP under Parallels, whenever open a document that is in a shared folder and then try to save that document, i get an "error disk is full" message. Cuirously, if I "save as" or create a new file in those shared folders, everything works. Is there something I'm missing, like a permissions setting under OSX or something? I'd really like to be able to seemlessly share files between OSX and the virtual machines.
