Yes.
The first time I opened it on a NODE host in regular interface mode, it gave me a dialog that it was in "Read Only" because the Project was also open on the Host that was trying to launch the job via Cluster Network. I closed that, and then it read without the warning.
It made my developer's mind think for a moment that the "checking the project isn't open elsewhere" feature might return as non-successful status that makes the batch NODE consider it an error, but I'm sure yourselves and customers who've been on ver 1.3.1 more a few months already would have already found and reported such a fundamental issue such as that.
In case it mattered, I tried configuring for Upper and Lower Case "W:" and "w:" in case the mount was case sensitive but no change in outcome.
