Undo command turns off by itself

[jhc65]

I am running AutoCAD 11. My undo command turns off by itself. I find myself having to turn on my undo command numerous times a day because it seems to just turn itself off. Any ideas what is doing it.

 

Thx

Sounds like you have something resetting it? Do you run any LISP or other third party applications?

Sounds like you may be using a lisp that is turning it off to run some functions but is not turning it back on afterwards, or you are cancelling out before it gets to the point of turning it on again.

Have you typed UNDO at the command line, and followed through the options, especially the Control option?

 

It might not now be set as you want it.
