[Gambas-user] DrawArea errors

[math.eber at ...221...]

   Try to do something like
   Draw.Begin(drawArea)
   Draw.Circle(10, 10, 5)
   Draw.End
   in one Sub, not in two. And not at all in the Draw event that is raised by
   drawing...
   Just look at all those examples in the Drawing section, plus ImageViewer.
