SO the problem seems to be within Motion 4 only. All other FCS3 apps function just fine. Motion is up to date and the problem occurs regardless of what else is running.
The issue occurn no matter what the project is… new or pre-existing. I have not adjusted the autosave values or cache – I will try that but my feeling is that it may not help. I’ll report back on that.
The only recent update was to Final Cut X. I am running Motion 4 and 5, as well has Final Cut 7 and X. All have been installed for a while now with no issues. I cannot be sure if the Final Cut X update is the culprit however I will uninstall and see if that remedies the issue.
I’ll report back when I have tried these two things.
