Hi Linda,
My IE6 was mess up too. Go to some website (like hotmail.com and it won't go pass userID passwd page). Im running win98, n was thinking mayb IE6 n win98 not suitable for each other.
As far as I know, IE cannot b downgraded n cannot be uninstalled.
My only solution is to use another broswer: Opera.
Wish u luck
SKy
