Hello, the best way to get a timely response to a report like this is to purchase support. If you don't do so, and you are using the free version of our product, your problem reports can end up queued up behind many other customers who have purchased support plans - they get priority!

Note of course that we always jump on bugs that might affect many customers as well as free users. But we have to prioritize by both severity and by whether the report comes from a customer that is supporting the product.

The warning you're seeing is harmless. In the upcoming releasing, AddTabClickedEvent has been deprecated and replaced with AddTabClickEvent along with the associated TabSet APIs, and when you switch to these the warning will be gone.
