I HAVE A WINDOWS 7 540s.  THE INTERNET EXPLORER 9 SEEMS TO NOT WORK WITH MY COMPUTER.  I KEEP TELLING MY INTERNET PROVIDER THAT WHEN I SEND AN EMAIL OUT. I NEVER GET A CONFIRMATION. I DELETED MY INTERNET EXPLORER 9 AND I AM USING INTERNET EXPLORER 8, WHICH WORKS FINE WITH ALL. . BUT I AM CONTINUING TO GET AN  UPDATE MESSAGE FOR THE INTERNET EXPLORER 9.  WHAT COULD CAUSE ONE TO WORK AND ONE NOT TO WORK? ANY HELP WOULD BE APPRICIATED.
