Why is c# Webbrowser not responding to clicks?

Question

In contact with

Hello, on Win10, I encountered a problem in webBrowser1 in my application:
The application has an authorization form in VK.
When you click on any buttons on the authorization form in webBrowser1, none of the buttons react.

Probable cause: just installed win10, worked with the program and started to configure the operating system. After I launched the program, and the form stopped responding to clicks, rolled back did not help. It doesn’t work on another PC either, or is it due to the fact that it was compiled on win10 ...
What is it all connected with, where to dig?

Replace "donkey" with Awesomium, CEF, etc.
