I tried to reply to a Forum post by writng in the Add comments to this post box at the bottom of the post and hitting the Post button. Nothing happened. I refreshed the page and tried again and still nothing. I then tried to use the Suggest Answer and this brought up a new page that allowed me to Post OK.
Ok I haven't tried it with IE8, but I did have a lot of issues with IE8 on other sites, that made me stop using it.
But that doesn't mean that we shouldn't fix it. Not at all!
I will start use IE8 again to test it my self. But I would love to know if there's any page load errors (shows in the lower left corner of the browser).
I don't usually get any errors. Sometimes I do but that's usually due to my connection and a refresh (F5) usually clears that up.
