Hello Chris,
The localization utility should show you the strings of all the panels and all the menubars in the UIR.
Try this experiment: load samples\userint\menus.uir in utility. It should show you strings for both
PANEL and
MENU. If it does, then that means that there's something specific to your .UIR that is causing the problem. If that's the case, would it be possible for you to attach your .UIR here, so that we could investigate it?
Thanks,
Luis
