Non nUI slash commands

[Peridoe]

Weirdest thing... there were a couple of times tonight that I needed to do a slash command and it wouldn't execute, wouldn't even show in the chat window. Earlier I was able to do /macro... but in ICC I couldn't do /range and /recount toggle or /recount show.

nUI is the latest new addon I have, so I logged out and disabled it. Both commands worked fine then.

I'm old, so tell me very slowly... how should I troubleshoot this quirky behavior?
