For the love of Crom, fix the chat window.
When I come back from a 10 min break, and a long conversation is going, I like to be able to do shift-up to scroll back, but it keeps resetting at the bottom every time someone else says something…
Shift-pgup, shift-pgdn, shift-up, and shift-down (And shift-end) should all control the movement of that scrollbar.
The way it is currently, is just horrendous.
