Yeah, I know - I took the idea from one of your programs. ;-)

The solution came from one of those newsgroup-shy RSI folks (thanks JP).
What I needed to do was to resize the draw *widget* instead of the draw
*window*:

drawid = widget_info(event.top, find_by_uname='drawwidget')
widget_control, drawid, xsize = event.x, ysize = event.y
info.oWindow->draw, info.oView
