IE7 and Vista

Just installed Vista Business as upgrade to WinXP home and endured 'many' updates so I have little history with Vista.
Problem: IE7 opens tabs but can't make the new tabs do anything or close with the red X.
Got one of the 6 open to do something when I clicked "learn more link" & a new IE window opens with previously opened 'tabs' :http://windowshelp.microsoft.com/Win.../internet.mspx

Now this 'new window' is the same each time, it just adds another tab & goes to http://windowshelp.microsoft.com/Win.../internet.mspx & that one is only partly functional.

What the ?><)++##@ is going on? What can I do to make IE7 work?
