Parallels Desktop 7 with Dual Screen

hey guys,

i have a problem with setting up the full screen mode of parallels 7 for my 2 monitors at home. i set up my virtual machine alright and it seems working so far but as soon as i put the windows 7 window onto the 2nd screen and change it to full screen mode, my initial screen instantly changes to the grey screen ( http://img.gawkerassets.com/img/17twub0tpj86dpng/original.png ) and wont allow me to use my osx desk while i am using windows 7 on the other screen.

is it possible to set it up in a way that allows me to see the win7 screen on one monitor, and the osx screen on the other?

thanks in advance for your help

greetings,
mark
