I was able to reassign a key to a different function, however when I close and reopen the Emulator the mapping doesn't save.  I did save to the default location for the keyboard file.  And thoughts?

Dear Chris

>>>> I did save to the default location for the keyboard file. <<<<

What exactly did you do by your statement above?  Did you take the action as described in this Technote?  https://www.ibm.com/support/pages/steps-map-keyboard-host-functions-using-access-client-solutions

When I tried opening my 5250 session and selected from its menu bar  Edit --> Preferences --> Keyboard, I then made one change to a Host Function key and then click SAVE button followed by OK. Then I closed the session (specifying NO for saving current session config) and then reopened it again and looked at the Keyboard map again, I saw my change was still there. No problem at all.  I did not specifically "save to the default location" at all.  

I then did another change and used Save As to the default file IBMi.kmp (in the picture below) and the change was still preserved.

When you select Edit --> Preferences --> Keyboard and then click the button Open in the section Keyboard File Options, what do you see? is it like this ? 

One thing you can do is to update your ACS codes to the current release. I'm using the emulator one release higher than yours  1.1.9.1.

Through a little more investigation I was able to figure it out.  Thanks.
