How can I get my toolbar back on Internet Explorer?

I used to have a regular toolbar at the top of my Internet Explorer home page. I mean that row of words near the top of the screen that says File Edit View Favorites Tools Help. But now for some reason that toolbar has disappeared. I can make it reappear temporarily by pressing Alt + t ... that is, the Alt key and the letter T key at the same time. When I do Alt + t then the toolbar reappears and I can use it in the regular way, but if I leave that page and then come back to it, then the toolbar will have disappeared again and I'll have to do the Alt + t again. I'm using Windows XP. How can I get the toolbar to stay in place and not disappear every time?
