Fullscreen

Quite simply, how do I get it? I have the option checked in the options but the game never goes into it. I have Uplink on 2 different comps (a G3 500MHz and a Dual G4 533MHz) and neither work for giving me a fullscreen game and I am stuck in the windowed view (ya I know, being stuck in the window is rather obvious if I am stuck OUTSIDE the fullscreen mode, bnut I just had to say it)
