[AccessD] Is IE8 crippled?

I must have been out of the loop but I have just installed the latest
version of IE8 on one of my test computers as I am doing a series of browser
tests for a new client's web site.

It appears the IE8 does not support IFRAMES even for local domains... This
is going to require a major rewrite with a lot of coding... as well it
screws up JQuery in various ways. To say the least IE8 looks like a
nightmare.

Any help or suggestions?
