Run The Shortcut To Stop The Add-in

I have an Excel add-in that makes use of an Application-level event handler to detect when workbooks are activated / deactivated, and adjusts the command bars / ribbon accordingly. The add-in also includes a developer mode, so I have a shortcut key to stop the add-in while running, set the .IsAddIn property =False, and then change whatever settings I feel that I need to.

Problem is, when I run the shortcut to stop the add-in, and then run my shortcut to restart it, my event handling no longer works. I've done some MsgBox testing, and verified that the class module's "Initialize" event gets called, but subsequent events (i.e. WorkbookActivate) go unnoticed.

I'm wondering if Excel will allow me to start an Application event handler using WithEvents, stop it (by setting the class module variable = Nothing), and then re-start the event handling.
