file error - the specified file is locked, Final cut pro

What exactly are you doing when you receive this message?

Are you importing a file? Exporting a file?

Are you having trouble with only one file?

I usually get this when I try to save a project and it isn't stored on my HD(usually external HD or RAID). Sometimes I can do a save as and save it to the desktop.

Sometimes everything is cleared up with a restart. It seems like it is a FCP7/OS developmental need which is mute because 7 is no longer supported by Apple.
