When I clicked on Create New Discussion, (using 800x600 resolution) I scrolled up to type in the box. The button to finish the post was off the page, so I scrolled that button up to middle of the page and then clicked on it. I was left looking at a grayed out screen, waiting for the closing box to appear. Of course shortly I realized I could still scroll and found the Close box with the 3 choices above that area. Not a bug or glitch, but an annoyance. It might be better if that last box, since it is smaller would float, anchored to middle of screen.
When I put in DivX thread, I clked on Create Discussion and then was left staring at grayed out screen. Tried to duplicate on TEST forum but didn't happen the same there.
