Mac mini with OSX 10.11.4
FM Pro 22.214.171.124
Using FM Pro 15 on the same computer that is running FM Server, I opened a file (remote) to access a file running under FM Server. The following error message appeared in a popup:
The temporary file "FMS_12A7A.... [lot's of numbers].....fch" could not be created on the system disk. Use a different name, make more room on the disk, or unlock it.
I have plenty of room on the system disk. I checked a script step that contains a Perform Script referencing a script in another file, and it had quotes instead of the script name. Trying to reselect the script, the script choices were missing.
I reverted back to FM Pro 14, and it works fine, so this is a bug in FM Pro 15 and not in my code.
