lisp routine deleting blocks it just inserted

[Anonymous]

I'm perplexed.

I've created a lisp routine to draw concrete caps on top a wall and then inserts a ID tags which is block.  It works great for my needs and I've been developing and using it for over a year on several copies of Autocad.  Recently, on one of the copies of Autocad, the lisp routine will delete the ID tag it just drew before drawing the next tag.  It will draw / delete / draw / delete / draw all tags leaving only the last tag drawn.  This only occures on one copy of Autocad even when using the same lisp routine.

Any suggestions?  Do I have a variable setting diffence?

Can you post the code?

It's crude and lengthy but works fine on other machines and copies of Autocad.  It even worked fine on this machine until recently.  You'll also need the block, TAG_PIECE.dwg, in your drawing.  I've attached a screen shot in hopes you find that helpful too.

ATTREQ was set to 1.  Changing it to 0 didn't help.  You're shot in the dark missed the target.  Sorry.
