Can't get display to fill screen

[RonArt]

I just installed VirtualBox (running OSX 10.6.8 as host for Windows 7)... and I can't get the display to fill the screen.

No matter what settings I use I still get a format that is square for some reason.

Any idea what I'm doing wrong?

Thanks.

Thanks... I'll give that a try.
