I am not aware of any recent problems. Are you having a long-standing issue? Is this any browser in particular? I know some browsers have some design problems with back buttons. I would also suggest your mouse button software may be an issue if you are using it for browsing.
It often helps to clear your cache and close your browser. Please post if you can narrow down the problem, or if you have details you can email me
