Just to let you know, I have Windows 7 Pro and it happened to me, starting today.

Here we go again. This is a problem on Chrome and now, it's on Opera. I need help. The browser size on my opera is now bigger and I don't know what's the problem with it. It's just gotten bigger and it's not supposed to be like that. It's at 100% percent size and the browser size is still big. Idk what to do. This is also happening on Chrome and it's making me frustrated. Help me?!

Same problem for me ! But I'm using Windows 7.
