Hey Hines232,
Does it show the IE Icon,just not any for the other websites you visit?
I guess thats kind of hard to check because IE6 does not have tabs,
so you cant open an empty one.
This happened to me when I used IE7,the IE tab was visible,but not the one for
google or any other site.
I cleared the cache and temporary files,rebooted and they came back.
Maybe you have already tried this,if not it is quick try.
