Assuming you have Parallels Tools installed and are using Version 1970...Go back into XP. Right click on the desktop and then select properties. CLick on the settings tab then change the screen resolution to 800x600 then select OK. You should be good to go now. Parallels Tools will automatically resize your full screen mode to the correct resolution eventhough you have it set to 800x600. If Parallels Tools is not installed, install it when in windows full screen mode. You need it in order to resize the screen correctly.
Note: This is fixed in RC2 3150 & RC3 3170, but because these are release candidates you may not want to upgrade now as these are not a full releases yet.
