Thanks for the reply Dave – I believe I have solved the motion prblm which was the 1st sign of a mac melt down. The green box in the Canvas was centered in the left 3rd of the window – not related in size or location to the imported motion file. But soon after it appeared, playing any FCP sequence from the timeline began ‘stuttering’ and audio/video were getting out of sync. Exporting, which typically takes a few seconds wanted 45 minutes, etc.
Other non FCP issues began cropping up – like all applications were running very slow, system sounds had stopped, and activity monitor showed FCP using 16.7 TB of RAM (I assume the TB isn’t referring to TeraBytes, regardless, it didn’t seem to be reporting the actual amount of memory in use)
Anyway, a lot of reading here & over at macosx.com lead me to install Disk Warrior which showed & repaired directories on 2 drives. Also installed and ran the Maintigit scripts.
All is well again.
