I had a similar problem with a very slow program a month
or so ago. When I profiled it, I was shocked at how much
time was being spent in ARG_PRESENT. It wouldn't surprise
me to learn that function graphics were twice as fast when
this problem gets fixed!

I have religiously used ARG_PRESENT in the GetProperty
methods of my objects. Now, I only use the function if it
is absolutely necessary.

Cheers,

David
