right. if i start a new window i get a different error:
ERROR: Message 'width' not understood. RECEIVER: Instance of SCWindow { (17AAF4C0, gc=AC, fmt=00, flg=00, set=04
also easy to fix :)
would you consider looking into relative size elements? it's very handy for different screen resolutions and of course expansion / contraction of guis.
( w = SCWindow("~", Rect(0,0,400,400)).front;
d = SCSlider(w, Rect(w.view.bounds.width*0, w.view.bounds.height*0, w.view.bounds.width*0.1, w.view.bounds.height*0.4)); )
