Hi Quark,


Thanks for the info, but unfortunately it's not just a matter of drawing
them on the screen, as the op system has to be told where to draw them
or else they will simply be redrawn at various times when the op sys
decides to.  Also, the op sys has to know where they are so it knows
if they have been clicked or whatever too.
Thanks anyway though.



Take care,
Al

And, good luck with your Euphoria programming!
