Improve error msg "PowerPoint can't start this feature because you currently have a Visual Basic for Applications project in break mode."
This message is displayed when there is an unhandled error in a customUI callback. It's extremely difficutl to debug as it can occur as PowerPoint and it's registered add-ins load. What is "this feature"? Which add-in caused it? Why can't we enter debug mode? I posted to @Office365 below and raised an in-app frown as this could affect many many users. This thread (with MVP input) demonstrates the Heisenbug nature of the issue: https://stackoverflow.com/questions/54432885/periodically-getting-vba-break-mode-error-messages-when-loading-ribbon-controls
