Create Layer Filter, and apply at drawing setup - everytime

[David_Knight]

Have a Lisp routine that was given to me that creates a layer filter.  I tried to add it to my acaddoc.lsp file so it executes at every file open.  I have it successfully creating the layer filter, but it will not apply it.  

This is the code I added to my acaddoc.lsp file.

(load "XREFNOT")
(c:xrefnot)

(defun-q S::STARTUP ( )
	(command ".-layer" "filter" "set" "No_Xref_Layers" "")
)

I added xrefnot.lsp to my autoload list of files.

Hoping someone here can help!

Thanks!

David.
