Removing ObjectARX without graphics

[pefi]

I keep getting this on each drawing in a set of 25 drawings

I tried this

(entdel (cdr (assoc -1 (dictsearch (namedobjdict) "AMAcad"))))

and it removed something, but the pop-up sill appears. Is there any method or removing it except copying the content into a new drawing?

It's funny how often the solution comes 10 seconds after posting a question.. I obviously purged the drawing, but I forgot that -purge all doesn't include registered apps. Problem solved.

Edit: for clarity - the lisp removes whatever was on the drawing and the purge registered apps executed after solves the problem.
