Custom RibbonX in one file interfering with custom RibbonX in another file

[kimkamp]

Hi:

I am seeing strange behavior when I have 2 Excel files open that both have the same custom RibbonX. It seems to hide all viewable RibbonX menus on the deselected file. And, the behavior seems to be erratic and randomly occurs.

Is there a way to isolate the custom RibbonX actions to the respective file, in two open files that both have custom Ribbon?
