Sometimes when I post in a thread using the quick reply box, I hit "post reply" button and I get a pop up with a "loading please wait" and a nice little rotating graphic, but it just sits there endlessly rotating even though you can see the post has been added to the bottom of the thread. The text still sits in the quick reply box as well. I generally just click out of it by hitting the forum or thread link to refresh the page and go about my business. Doesn't effect my ability to post, just for your info.
