I have noticed the changes in your website, demos and documentation, but not all seems to work well on IE 11.
In the new interface of
the left menu dissapear after more clicks (IE11)
However, in ASP.net AJAX demos, the new interface is not looking good on IE 11
For example, https://demos.telerik.com/aspnet-ajax/orgchart/examples/expandcollapse/defaultcs.aspx
The old interface was looking great, I had no problems at all, any control
I hope I will not have the same problems in my ASP.net application...
