Figured it out. Ran the back trail through the launcher and deleted the hazardous save file for the mapper configure, and it's fixed!

@mirekluza , any suggestions would be helpful please.

In trying to get some keys to register differently, I have mistakenly caused my ctrl keys to not function, is there any way to restore the keymapper to stock settings? I have tried uninstalling dosbox and it has retained the settings once reinstalled.
