ya, that's what i ended up using... :) for maximum compatibility (the 
mac i was testing on didn't even have the GUI class ;6 ) i wrote 
something along these lines

{
GUIHelper {
	*window {
		if (\JSCWindow.asClass.isNil, {
			^SCWindow;
		},{
			^JSCWindow;
		});
	}
	
... button, slider, textfield the same

}

i know there are more elegant solutions (such as that in GUI itself) but 
this works nicely for a simple fix

cheers!
