Addr. line problem with IE6..Any1 else?

I'm running WIN98SE (fully patched) on a P4 machine using IE6 browser for over 3 months. A new problem has surfaced in the last week concerning the Address Line in IE6, I would like to know if there are others having the same problem which can be corrected then repeated at will.

I use http://www.yahoo.com as my home page (just for load speed reasons)

I can type into the address line a correct URL while surfing or click on any of my favorites and the browser calls up the page to connect, before loading the page however the address line URL will switch right back to my home page address. This repeats relentlessly recently.

My fix for the problem:
I can run thru the use of Add/Remove Programs the check & fix utility for IE6 and the problem goes away. At least it does until the next time that my Nortons "One Button Check" runs (which I have set to run automatically thru Windows Task Scheduler as part of a regular maint. schedule),
when the OBC runs, it picks up an entry in the register that is incorrect (the problem w/ the IE6 addy line I believe as the problem seems to arrive again right after the OBC "fixes" the registry problem).

Has anyone else seen or suffered the same problem? Any suggestions short of replacing the browser w/ IE5.5. Could this be caused by the latest IE6 Cumulative Patch? Can you point me in the direction of any tech bul. you may have seen on the subject?

Thank You All.
