FileMaker 13 Pro on Yosemite has a problem with the Temporary Folder
Operating system version
Description of the issue
With Yosemite, FileMaker's Temporary folder seems to expire or time-out or otherwise 'get lost' in longer work sessions. Scripts that attempt to access the folder will work as they did in Mavericks when first launched. Later if the work session becomes lengthy errors are thrown up about how FileMaker can't find its temporary folder. Restart Filemaker and those script steps work again. I turned off App Nap but that didn't fix it. There definitely seems to be a temporal aspect to this bug. I've seen it now about 6 or 7 times, all in the same context.
Steps to reproduce the problem
1. Use FM 13.03 and Mac OS 10.10
2. Leave Filemaker open 1 hour
3. Try to save to Temporary Folder with FileMaker script's "Get(TemporaryPath)"
Write to / access to temporary folder (PDF file being created in this example)
Filemaker error about not able to find temporary folder
