When I start Windows Vista in 'Single Window' mode, the text is clearly readable, but when I change to 'Full Screen' mode, the text is not as clear anymore. When I go back to 'Single Window' mode, the text remains less readable (see attached image; top is how it should be, bottom is after switching to full screen). Before SP1 I was able to correct this problem by changing the window size by dragging the bottom right corner of the window before switching to 'Full Screen' mode, but this does not work anymore. I just reinstalled Parallels Tools, without any change. I'm using PD 5584 on an 24" iMac (1920x1200 resolution) with Mac OS 10.4.11. Any help would be highly appreciated.
