Tim,
I was merely going to say, that you should design your UI to look and act exactly the same as the AutoCAD UI. The rule I follow is that if there is no precedent in AutoCAD, UI wise, then I won't do it.
However, seeing as you're doing it for yourself, that's a different story, but I would still suggest that you follow the standards, per se.
I'll have a look at your code file on Monday and see what I can see
By the way, are you aware, that AutoCAD provides an attribute extraction command and more recently, an enahanced attribute extraction command called EATTEXT as part of the core commands?
Cheers,
Glenn.
