I've not tried that yet , but in the publish dialog box, there is a checkbox wich insert compatibility code for IE6, 7, 8.
It's called Google Chrome Frame for IE6 7 8
I can't get it to run with IE8 either and thats with the tick box ticked.
Did it work for you?
No unfortunaltely it didn't. Honestly I gave up and ended up creating the website in Muse because 99% of the users of the website I created were IE...
