i think its cuz the window width and height get stored in some prefs somewhere,
you can get round this by editing the -w -h flag after you do the showWindow comand
Code:
proc tweakWindow(){
if(`window -exists SGTweakerWindow`){
deleteUI SGTweakerWindow;
}
string $tweakWindow =
`window
-title "Tweak v 0.1"
-s false
SGTweakerWindow
`;
showWindow $tweakWindow;...
