Hmm, well my game is 320x240, and my GUI is 161x200 with no transparency on top or bottom. With just CentreGUI used, it centres it horizontally but it sits exactly at the top of the screen. I'm using AGS 2.61 so perhaps it doesn't work in this version, but you wouldn't think so.
I haven't used any other SetGUIPosition functions or anything anywhere in the game...
