Lisp gets stuck (not in a loop)

[hencoop]

I cannot find anything on the internet about my latest problem with AutoCAD Civil 3D 2017.

It appears that a lisp routine gets stuck (not in a loop) just fails to finish and release LISP so that the following error messages are produced instead:
"Can't reenter LISP"; "Unknown command .VLIDE". If I try to enter any lisp statement, e.g. (), I get "lisp command not available". Nothing I tried could release autolisp. I had to shut down AutoCAD and restart it.

I have only used lisp commands/functions that I have used constantly for years now, so I can't understand what has caused this problem.

This typically occurs when there is a loop that causes autocad to use all resources allocated for lisp. Can you post the code? Or send it to me via email?

Jeff,

I meant to reply earlier.

I to appears to be in some old lisp code that I have used for years to invoke the correct editor for anything that is text whether its entity name is "TEXT" or not.  I see that there have been some changes over the years in AutoCAD to do just that which went right past me as I kept using mine.  I'll send you the code if you like (PM) but I started editing it before I figured out that I probably don't need it any more and I'm not sure that it will still cause the problem (or even function).  I was right in the middle of edits when I decided to abandon it.  Hey! I have an unedited version on my website that I will link.
