After making no changes, my guest OS (Windows XP) is not following the resizing of the actual Mac window, when running in a 'windowed' mode. I can change the display manually within Windows, but cannot maximize the Mac window and have Windows auto-adjust. Frustrating. I have already reinstalled Parallels Tools. A couple of other curious things are that it will not switch to any other viewing mode, except for full screen. And the mouse cursor that used to disappear and transform into my black arrow when I reached the edge of the Window environment and disappear from the Windows environment, now stays on the Windows screen, at the edge of the Window. (I know that last bit sounds a little confusing). Please help
