Addin Problem: Events for CommandComboBox in multiple Windows

[Oisin]

I'm writing a COM Addin for Word2000 with my own CommandBar containing
Buttons and Comboboxes. My problem is, that the eventhandling for the
Comboboxes only works in the first document window, while it doesn't
in any further document windows created.

I've searched the usenet and found the following:

Custom menu items in Word require a Tag property to properly handle Click
events for multiple windows. Try adding a unique tag to your menu item and
see if that resolves the problem:

mMenuItem.Tag = "Click_Me"

in http://groups.google.com/[email protected]

The solution provided does only work for CommandButtons but not for
CommandComboBoxes.

Has anyone got a solution for this. Is there any undocumented
workaround like the Tag-property for the buttons?

Thanks in advance,

Oisín
