I've been trying to support an issue with IE8 where when a user clicks the back button, then the forward button, the back button becomes disabled. If you google for "IE8 back button stops working" you'll see that I am not alone. No one out there has come up with a solution for this yet. Short of having to reinstall IE8 on every machine(many, many machines) I was hoping ask and find a solution. Thanks!
Edit:
I've tried running IE8 without add-ons and restored the settings of the browswer and neither worked.
