Internet Explorer Question

Hi,
I don't know if this is the correct forum for this question, but hopefully someone will be able to answer. Earlier today when I used Internet Explorer there was only one space for it, or one window at all times, even when I attempted to open a new one. And next to the little "e" logo there was a number, which was the number of "screens' I had open. I could hover over this and see a history of the places i was visiting.

My question is, now this mystery feature has disappeared. How do I activate it again? Thanks!

 

try the IE6 menu for tools ! internet options ! advanced ! and restore defaults and see what happens.
