I'm trying something new tonight when making a post. I prepare the post in the response window, open a NEW copy of the forum ("Active Topics") in a new tab (using Firefox), then go back to the first tab and submit the post. The posting tab locks up, but the newly opened tab stays usable.
It's been successful one-for-one so far. Now to try it again.
P.S. Anybody notice how "Preview Reply" works fine without any lockup problems? Does that go back through the server like an actual reply does?
