PowerPoint vba - Event not fired when screen is empty

[VeronicaStr]

Hi Paul, thanks a lot!
I immediately implemented your code into my PPTM. I saved as an add-in, but now the events do not fire at all...
I first tried it without the btnAction code (as I want the custom groups to be visible only by checking the template name, not by clicking a button), but then the custom groups did not appear.
Then I put in only the first part (btnA, btnB, btnC). My custom groups are quite extensive, so I thought that would be better. When I click one of the buttons, my custom group appears. But the Ribbon does not refresh on opening, starting new or closing a presentation.

There is one other thing I don't understand. The code does not declare what bFormatA, bFormatB and bFormatC actually is. In my previous code I referred to the tags of the groups in the Custom UI ("MyPersonalGroup1" etc).
Should I not declare that somewhere?

I could send you my complete code if you want to take a look at it?

Thanks for your help!
