So I've set my WinXP 'My Documents' up to use the Mac 'Documents' folder. Loving the integration with setting Mac documents to open in Parallel Applications (nice touch!) Here's the issue, which seems to stem from cross OS file system refreshes. - on shared folder in virtual OS, copy/past a file - note that you must manually hit F5 to refresh I did this real quick and tried to open the resulting file in MS Project. Project just complained that the file could not be read. Slightly annoying, but not a deal breaker. :0)
