Question
I have downloaded a LISP program (Hot Tip Harry collection) and it has worked fine. It's a program to add text along a polyline in a map drawing. Lately when I have tried to use the program I get the following: " No Function Definition:  VLR-Mouse-Reactor"

Any suggestions as to why this is now causing the program to be disabled?

I have had traing in the use of autocad and autoLisp.

Thanks

Answer
Hey, sorry, you have asked someone who is not much of a fan of lisp, at least as far as creating one's own goes, but I am a good sleuth, or try to be.
My experience found SOOO many people trying to keep their customization from R12 or R14 into 2007, even when AutoCAD had progressed, and it would seem better to try the new ways, later add back in only the most essential customization.  I DO see the point to the routine you are using, for your purpose.
BTW-- I have purchased add-ons based on lisp for clients, and I believe the Hot Tip Harry stuff to be well regarded.

Since you made the (sorry) big boo-boo of not telling me which AutoCAD release you are on, and listing all other programs, add-ons, etc  -- I could not be very specific, even if I were the Lisp Daddy -- lol
BUT-----------
1-- see if you have installed something else that is interfering.
2-- remove and re-install that routine (PS-- I see this is mouse-related, but I am fond of putting all this kind of thing on a tool palette, with all tools for whatever aspect of the project I am working on, since 2004)
3-- see if Norton Systemworks or some other cleaner messed up the file (spyware cleaners take out a cookie, making ADT  half useless, for istance, and you have to reinstall the program)
THE POINT IS THAT IF IT ONCE WORKED, YOU HAVE CHANGED SOMETHING OR ADDED SOMETHING THAT MESSES IT UP --(assuming you have not installed it on  a newer release of AutoCAD with which it is incompatible) -- programs dont break themselves..........FIND, FORGIVE, AND FIX
4--Since you really need a lispomaniac if it is not one of the above, look for lisp discussion groups/forums on Autodesk.com (under AutoCAD groups), AUGI, Cadalyst, etc. (I got a lot of Google hits on <<autolisp forum>>
GOOD LUCK
