Is anyone using the Nostromo with AutoCad?

I'm an architectural designer and draw house plans for a living these days. I upgraded my Nostromo software a while back and some of the buttons don't work the way they used to and it's quite frustrating.

For example: The 11 key on my Nostromo used to type f0 which is a command I have written in AutoCad for Fillet 0. Say you have one line going East to West and another line running North to South. The lines don't connect. Using Fillet 0 allows me to select the ends of each line that I want to connect, and they will connect together..

With this newer version of the Nostromo software, it won't do anything of the sort. Basically is just types f0 in my command line, if it had a return or enter key, then it would allow me to click the two ends and they would join together.

I realize I could just extend each line over each other, then trim them but, that's really not the problem. My older software allowed me to have Autocad Lisp routine loaded and when I hit the key with f0, it would be asking me for the two lines.

Any help is greatly appreciated.
