Vista - Offline Files Showing "Not Available"

I'm using offline files in Vista Ultimate on my notebook to sync with an XP
Pro desktop. In general it works well, but with one application (Solidworks)
as soon as I open one of it's documents on either computer that file will not
sync. The files show up as Not Available in the directories as soon as I
either switch to working offline or disconnect from the network. A manual
sync will run to completion, and doesn't throw any errors but the file
remains unavailable. The only solution seems to be to restart both computers
and then do a manual sync. More than a little hassle everytime I try and pack
up the notebook. Atleast in XP it warned you if something didn't sync
properly. Any suggestions?
