Wilfried,

Thanks for the response. I have solved the "problem". I was initially adding say 99 shapes based on 99 defined locations. If I then added a 100th shape at a 100th location all was fine, but when I attempted to delete the 100th shape the ring would appear. I was using an index of 100 to delete the shape. However I found that if I instead used an index of 1 the ring did not appear. If I then move shape and location 100 to another position(after the shape being deleted) the shape is again shown correctly and again, I need to use index 1 to delete it. I guess the delete is based on a "most recent" basis which is a bit counter intuitive.

Again, thanks for your help and suggestions,
Bart
