Can't receive event from Command Bar Button

[London Developer]

Hi,

I've created a VBA COM Add-In that creates a command bar with a "WithEvents"
declaration in my code.

I debug the VBA in Excel, and obviously test the add-in in Outlook.

When I'm running in debug, I cannot get the code to pick up the button press
on the command bar - it just ignores it. When it's compiled as a DLL it
appears to work fine.

Is there anything I can do to make my debugging a bit smoother? Am I going
about this in the right way?

Thanks
