I am also having this problem and can't seem to fix it. I have read back through a years worth of this message board looking for any related posts and I have tried suggestions to get no result.
I have tried un/reinstalling several times, downloaded another copy (after trashing all old) , updating mrj, increasing memory to mrj. HELP!
I am running 9.2.2 on a G4 500 D/P 512 ram connected through ethernet to cable. I shouldn't have any trouble but am stuck.
cheers
Andrew
