I've used IE8 since it's first Beta without much of a headache. The final released version has been working great for me. And it's worked perfectly with WebCT since December, despite what ISU's computer group says.
I'd recommend upgrading.
every time I load a page I get this nag that I am "running with add-ons disabled, click here to manage,disable or remove your add ons."
How do you get rid of the nag?
