OSX Server Screen Resolution

Hi,

love using Parallels Desktop 6 on my macbook pro it just works better then vmware

altho i have one problem, i cant seem to get my osx server to stay at one screen resolution...

it keeps saying i cant use the 'Server Admin' unless i have a screen resolution of 1024x768,

so ive installed the Parallels Tools and when i enlarge the screen in 'Window' view, i can only get '1280x688'

is the away of telling the Parallels Window to scale the Screen Resolution rather than using the full resolution of my MacBook Pro Window ???

Cheers

Simon
