With two networked computers, if we create a Koolmoves project on one computer in a shared directory, it can be opened and edited from the other computer. But if we try to save it (back to the other computer), we get the hourglass forever, losing the edits. A workaround is to save it locally then copy it, but any ideas on what the problem is and how to fix it.

Windows XP restricted account, latest Koolmoves 4.6.5.
