If you mean the "back" button on your browser, I have noticed this as well on occasion. Sometimes when I click into an article here on FR, it somehow reverses the position of the article and the main page list. When this happens, I can either click the "forward" arrow, which will take me to the article listing page again, or just close my browser and reopen. I'm not sure why it does this, something to do with the way the FR software creates the individual article pages.
I've never encountered this kind of problem before. I guess the old saying, 'there's always a first time for everything' applies here.
I'll give your suggestion a try. Thanks.
