Can someone please help? I can’t seem to make Object Reactors persistent (see code in routine CreateObjectReactor-QtyChange below). When I open a drawing with Object Reactors I created, I receive the following messages: Opening an AutoCAD 2000 format file. Regenerating model. ; warning:erased VLA-object restored to NIL ; warning:erased VLA-object restored to NIL ; warning:erased VLA-object restored to NIL ; error: VLISP: internal: Document application(.VLX) not found ; error: VLISP: internal: Document application(.VLX) not found ; error: VLISP: internal: Document application(.VLX) not found AutoCAD menu utilities loaded. This is with no customization at all (acad.lsp, acaddoc.lsp, MyMenu.mnl, etc). What am I doing wrong? Also, am I doing the “active document only” notification correctly? Will this notification be persistent? (defun CreateObjectReactor-QtyChange (object-list app #leader-text / hole-reactor)   (vl-load-com)   (setq     hole-reactor     (vlr-pers       (VLR-Object-Reactor         object-list         (list app #leader-text)         '( (:VLR-erased . UpdateHoleCalloutText)            (:VLR-copied . UpdateHoleCalloutText)          )       );VLR-Object-Reactor     );vlr-pers   );setq   (vlr-set-notification hole-reactor 'active-document-only) )
