JK2 not loading in primary monitor in dual monitor setup

[Hunnicutt]

I'm running a Powerbook G4 12" w/ an external ViewSonic 22" in a dual monitor configuration (not mirroring). The ViewSonic is my primary monitor and all apps open in it. After going on a roadtrip and playing a couple rounds of JK2, I've come home, hooked back up to the ViewSonic and now the game loads only in the 12" Powerbook. Any ideas to get it back on the big screen?

 

Thanks!
