hello: my first post & i am very new to this software. i have installed windows 2000 & i can only get 16 colors with 640x480 screen area. this sucks because i have a mac pro quad core 3ghz with dual dvi 20inch montors sporting a radeon x1900 card. . .& i was hoping to have a pleasant viewing experience in the virtual machine. have i done something wrong or not activated something on installation? i have tried troubleshooting & it refers to tabs that are not available.. . . help? thanks in advance!
