Hi, I have some lisp, vlisp and reactor programs, and, since a while, when I am in a new drawing, the first function of mine that I activate, if that function have a setvar something..., the function will crash. Then, I retry the same function and it work ! That also append when I come back from a Layout to Model Tab, if the first function that I activate have a setvar something..., it will crash. Is any one have an idea of the problem ? Thank
