[Problem with the window screen]

Yep, thank you

 

[Problem with the window screen]

I have a problem with the beginning menu when you start any viewer.
So basically I do not know what I did but... somehow the menu is oversized and I cnnot like drag towards the login spot because it doesn't show up
I only see my username, password and the link where it says "forgot password?"
If anyone can help me, please do because..
My whole screen is zoomed in and I can't zoom out.
