I have a text editing Lisp routine that runs perfectly, except just occasionally during intensive use it throws up an error message and bombs out:
Unexpected exception in lisp main! Error: ÜûáPO*Cancel*
What does this mean and is it likely to be caused by an error in my code?
This particular problem occurs in AutoCAD 14. I've yet to run the Lisp routine in a later version of AutoCAD.
