Error: 'AutoCAD variable setting rejected: "cmdecho" nil'

Brandon,

Well first, you are not closing a command, you are pressing Esc. Ending a command by pressing Esc is the equivalent of exiting your car by using the ejection seat.
To instead exit like a gentleman, you should be Right Clicking, which allows the function to perform any necessary cleanup work.

But this error in particular, was due to a very short-lived bug many versions ago. When you start up AutoCAD, press F2 -- what version number of Land F/X is loading? This has all the hallmarks of an errant landfx.vlx being loaded, or just being very out of date.

Well the ejection seat sounds like fun, but using the esc key is what I use when I hit the wrong command and want to back out of it instead of having to follow the command all the way through. More like putting the car in reverse because you took the wrong street....

...you do realize that reversing because you took a wrong turn is not only really unsafe but also against the law, right?

Well, that's the latest version. So now you just need to give us exact steps on what you are doing.

Well after closing everything and re-starting AutoCAD to provide the above information for LandFX version. I am no longer getting the error prompt. So I apparently wasn't holding my mouth right or something this morning. If it happens again I will take notes and provide you an update.

As for backing out of a wrong turn being unsafe, depends on where that wrong turn leads you.
