Options don't pop up for lisp commands in 8.2.6

Since going from 8.1.6 to 8.2.6, my lisp commands no longer make the option dialogs pop up.For example,

(defun c:Q () (command "SelGrips" "Pro"))

used to give me the same pop-up as typing "Selgrips Pro" at the command line, but now it doesn't.I have FILEDIA and CMDIA turned on, and no hyphens or underlines in front of the commmand names.Is there any way to restore this functionality?
