Would VMWare Server do any better for you? Try that out for size, and see if that one will do a far superior job for you.
I'm considering getting VMware. But if I go over my 1GB datacap it will cost me another $10 for 4GB so I want to make sure that it will be worth while - so, does anyone here have an experience with VMware? Does it do a better job than VirtualBox when it comes to fullscreen applications?
