Parallels Desktop defaults to full screen on Mac/os after starting the guess machine which is windows/xp. Since parallels desktop expands and fills the Mac screen, Iam forced to slide the oversized window to left to get access to the buttons that start , stop and invoke full screen access to the guess machine (windows/xp). Appears to invoke the windows/xp welcome screen in full screen mode before I depress the (F/S)button on paralles desktop. This didn't happen until I added sub accounts(users) to windows/xp. Its annoying to flip back and forth from windows/xp and Mac/os to see the full screen of windows on the Mac. How to fix? thanks ahead. osusam.
