[Newbies] creating smooth graphic in squeak

I have only just started playing with squeak and I suspect this is a very very basic question!

The graphics in the squeak environment -- and by that I mean things like the lines drawn round boxes and even the little widgets of the closing windows etc -- seemed to be very primitive. They seemed to lack the anti alias smoothness which you find in, for example, flash. I've tried running squeak on both Windows and Mac, and the graphics do seem smoother on the Macintosh. So this makes me wonder if there is a setting somewhere in the Windows environment which I have missed. To put it another way, is there a way to get squeak to use the native Windows widgets?

Thanks in advance
