I am having a wonderful time trying to resolve this issue.

I have a .NET Com Add-in for Excel, I create a menu and a toolbar inside the
add-in. Every so often my Menu Items stop responding to the click event.
The click event never fires.

The matching toolbar button continues to work though?

I walkded through the with the debugger, ran traces and cannot not see any
exceptions or errors occuring.

CAN ANY ONE HELP ME?
