I'm not an average Internet user.
Opened and ran my own ISP way back in '94.
(The first dial-up provider in 2 counties where I live.)
Sold that then did Networks for all the Lawyers and Court systems here.
I've also Beta tested every version of Windows since 98
I am seeing NO problems at all with IE8.
Then again maybe my Router is catching them.
It's not your average Wal-Mart router.
