Since I cannot do this by manipulating 'menu extent: ...' directly, the only way I found until now is to manipulate the image form 'menu image: menu image scaledToSize: ...'. That works pretty well except for one thing: I cannot change the aspect ration of the original image with scaledToSize:. Since I do not know the extends of my menus before the game starts, I cannot say anything about the needed image ratio. Since my menus should be as applicable as possible I need to be able to resize also in a way which destroys the original scales.

Wouldn't it be simplest to just use a regular MenuMorph and give it a BitmapFillStyle?

	MenuMorph example
		fillStyle: (BitmapFillStyle fromForm: ScriptingSystem squeakyMouseForm);
