Benoit,

i sent already, but maybe attachments has been rejected.

The code below creates 1 circle. After resizing in GB3 i got
4 circles. Doing same in GB2 just a resize of the area is performed
and the primarly created circle persists.

Public Sub btn_test_Click()

 'Drawing Area set to 100, 80 
 ' DrawingArea.cache - True
 '- - > 200, 160

  Draw.Begin(DrawingArea1)
    Draw.Circle(50, 40, 30)
  Draw.End

  DrawingArea1.Resize(200, 160)
  
  myPicture = DrawingArea1.Screenshot()
  myPicture.Save(ProjPath &/ "circles.png")

End
