what’s your monitor set up ?
are you using 2 monitors? is one of them VGA or as a VGA to DVI adapter?
this seems to be the problem, when you’re running FCP 7 from the internal startup disk.
when booting up and launching FCP if you see your canvas and viewer white.
quit FCP, unplug the monitor that’s VGA or VGA to DVI, go to display pref and select detect display, then relaunch FCP.
hope it helps
