At least latest revision has changed behaviour of circle keyword (in Qt4). This doesn't draw red sector, instead it seems to draw some part of it which doesn't start from x,y: Draw.Foreground = Color.Black Draw.LineWidth = 1 Draw.FillStyle = Fill.Solid Draw.FillColor = Color.Red Draw.Circle(x, y, iSize, fStartAngle, fAngle) Jussi
