Help with OS/X and HP-IL on 41CL

[twoweims]

I have been using my 41CL with the OS/X (OSX3) module plugged into page 7 without issues.

Recently I was lucky enough to get an HP-IL Module, an HP 5384 Frequency Counter and an HP 3468 Multimeter. The module and the instruments work fine.

The problem is that when I move the OS/X module from page 7 to any other page it loses some functionality. I am unable to use the Enhanced Catalogs or the Extended XEQ and ASN Functions. I can execute individual functions and the prompt lengthener works.

This is my first experience with an HP-IL Module so I must be doing something wrong.
OS/X should be compatible with the HP-IL Module since the enhanced catalog has functions to list the HP-IL Catalog.

Is OS/X only compatible with page 7?
I would like to keep pages 6 & 7 open so I can use HP-IL or my IR Printer module as needed.

UPDATE: I have verified this behavior on two different CL's. Both are V5 with the 5/2/2020 Updates.
