There is still the cut and paste issue where your text appears (only to you) as the font style/colour of what you pasted until you close the chat window. This problems been around since the first 2.0 beta the devs know about it, but it still hasnt been fixed. There are also some UI drawing issues now to beta 4. Like the status drop down box for me has 3-4pxls of white on the left of it.
