I did reply to this last week, I guess it got lost.

I solved the problem thanks Lewis.  A number of things were causing it..
Firstly it was a line primitive, not a sprite as the error message states
causing
the problem, this threw me a googlie at first.
Next the cause of the error was due to a bit a bone head code on my behalf
passing a negative number as the priority of the line.  Understandle really.
The thing that really stumped me was the message about a sprite when infact
it was a line causing it.

Cheers

Jim
