Okay - after a little playing with my windows screen resolution, I have it at 1920x1200 which seems to work. I don't know how I got that choice and did not get it before. hum... but it seems to satisfy my issue now and my SW sketch circle looks like a circle. I think it might have something to do with my 2nd monitor and the fact that I like to "extend" my desktop and have my 1st monitor as my primary (i.e. taskbar and desktop icons.) I also can only get 1600x1200 on my 2nd monitor but I think that is because I'm using a VGA instead of DVI cable.
