Better change to a dual boot with one of the current Linux-Distros. After testing about ten distributions, I recommend Kubuntu, the KDE desktop is the nearest and most intuitive at the moment. It is also, from the most used Distros, the most stable one. Then you can run Scribus in its native environment, Gimp too. And in a year of two, you dont use Windows any longer.$
Give it a thought. It will pay out.
