In game press Esc, go to video and select windowed mode (the way the other's described won't work )

How could you possibly play Spore and FSX at the same time? :S It shouldn't even run.

I tried running spore on a dual monitor setup and THEN i tried running FSX.... I forgot to put them in window mode..
