Works fine for me with IE7 on XP. Don’t even get the popup as I have Axiom set as a trusted site.
On the other hand, often, when I click the "Preview Post" button I get a "Preview Loading" indication and the green line moves slowly across but never completes it's journey and the preview never loads. If I then click the "Send" button, the same thing occurs - green line that hangs about half way across forever. However, if I close my browser and then reopen it, and return to the forum, I find that my post did make it into the thread. Weird.
That also happen to me but only very occasionally. Hitting the back button and then re-clicking on "Preview Post" or "Send" takes care of it for me.
