Hi Chris,
What I am doing is creating a surface with p=surface() and then
rotating it in a loop with p.rotate,1,/zaxis. The problem occurs when
I break the program execution in the rotation loop using ctrl+break.
The problem occurs most of the time, but there have been instances
where I have been lucky. This is a new piece of code I cooked up
today, so this bug may indeed be preexisting, I have not tried older
versions.
