When IE7 was designed they took the peculiar decision to split the navigation buttons into three places (if you include the home button).
If you find yourself up in the top left wanting to reload, just click the drop-down button and select the current page (will be highlighted and have a tick-mark on the left), as shown in the picture.
Bizarrely and unfortunately, this only works if you’re not looking at the last page in your navigation history for this tab. This suggests that it’s only through poor programming logic that it works at all.[tags]IE,IE7,Microsoft,tip,tips,browser,flaw,bug[/tags]
