It sounds like the issue here isn’t Windows (or Windows 8, in this case), but the browser that you’re using.
As of this article’s publication, Windows 8 is still sort of new so it is a little early to say yea or nay. But I suspect that you’re accessing the browser (I’m guessing Internet Explorer) from the tiled Start screen.
That may not be the browser you think it is.
Two versions of IE on Windows 8
The tiled browser is a slightly different version of Internet Explorer than what you’re used to using. From what I can tell, it seems to have somewhat reduced features and it’s less than completely functional when compared with the normal Internet Explorer.
So, what I would have you try is instead to click on the desktop icon. If you’re not already at the desktop, use the Internet Explorer icon that shows up in our traditional taskbar down at the bottom. That seems to fire up the traditional, full-featured Internet Explorer.
Of course, there is another approach as well.
Try another browser
If you still have the problems with that, the other solution is to consider firing up a different browser. Try Chrome or Firefox. They’re both fine browsers and work on Windows 8. They should be able to run properly and there isn’t this confusion of versions depending on how you start it.
So I would give Internet Explorer from the desktop or taskbar first. And if that doesn’t resolve the issue, then fire up something like Chrome or Firefox and see if that doesn’t clear it up for you.
