I don't know how it works.
I'm just trying your exe file and it keeps refreshing the browser every second and skipping without any chance to solve captcha  

and why you didn't provide close button? in windows 10 x64 it doesn't close the app window even though through right click - close window.
I should open task manager to end this task.

PS: how to add proxy to this app? as i always using my private squid proxy in browser.
