Question : Invalid Custom Toolbar message

When I right click (half the time inadvertantly) on a form, I keep getting the message:

The custom toolbar XXXXX  is the wrong type (menu, shortcut menu, or toolbar) for the property it's being used in.

This was caused because earlier I was trying to learn something about this feature and succeeded in finding the property and assigning the XXXXX toolbar to it.   Now I can't find the property again to remove it!

Question:  Where is this property located, and how can it be accessed and modified?

Thanks!
