Look, if you have licensed updates period, you get updates. If you do not have, then you cannot get updates.
We do not have a special policy for those who found a bug. We just provide control and its updates for a certain period of time according to license type, that's very very simple.
Yes, I thanked you for helping to find the issue. And can thank you again. It doesn't really matter whether you have license or you are using trial. I didn't really care whether you updates period expired or not. We always accept bugs, help solving issues, answer technical questions related to treeview for ALL users (trial, customers and those whose support period already expired). We can be proud of how our support goes.
