It seems to have been this way with my windows xp and I can't really figure it out either.... Maybe in the desktop settings when you right click the background?
When i first had xp it did the same thing but after a few times maximising it, it automatically started doing it itself. No luck on vista so far unless someone knows another way.
Stretch the window to the size you want, then right-click the minimize button and click size, then click again in the window. Should be fine after that. :thumbsup: :wave2:
