What is wrong with Internet Explorer 8

What the heck is going on with MS Internet Explorer version 8.0.
Most times [but not all] when I right click on a link to either open in a new window or new tab, they open but the page never comes in. So I'm on a site which I want to remain open, right click the link to display in a new tab. Well the tab opens, but I just get the hour glass [for ever]. However the page opens immediately in the original window or by pasting the address into an already open tab, I can get the page to open in any other window.

So what is the deal with MS IE 8 about opening new tabs or windows?

I use three different browsers in two different displays to open up three different sets of web pages, so I still want to use IE even if I have problems with it.

I'm using IE version 8.0.6001.18813
