Hi Art,
Have you tried going to Control Panel > Internet Options > General,
eliminating temporal files and rebooting?
If still no joy, it might be a malware issue:
Download the utility CWshredder:
http://www.spywareinfo.com/~merijn/files/cwshredder.zip
Unzip - close *all* instances of IE & OE, hit the executable and
follow
the prompts.
You can also download Hijack This from here:
http://www.mjc1.com/files/merijn/hijackthis.exe
Go here:
http://mjc1.com/mirror/hjt/
For instructions on how to use it; you have to post the log it
produces so experts tell you what is good and what is malware
Try downloading, installing and updating the
spyware removers from the links below. Run both of them.

Spybot S&D

If these don't correct the problem, then get yourself a copy of
BHODemon, available at
http://www.definitivesolutions.com/bhodemon.htm .
It does not need installing - simply unzip and run the EXE program. It
is easy to use. It will find the hijackware DLL files, and give you
the ability to disable them.
If this does not solve the issue, try reinstalling IE:
