Not sure if reported yet, but the page-up button doesn’t work correctly on Exalt. On Flash player, when you click page-up (say in USW3), it will freeze at the location you scroll to, so you can pause to read it. It doesn’t do this on Exalt (at least for me).
Also it just seems bugged out in general. Sometimes it reverts back to some previous segment of chat, and there is no way for me to view recent chat except for hitting enter to start a message.
It’s trivial, but quite annoying for me…
