A couple of my guys swears by the Opera browser.
They observe that many of the Track Studio pages are rendered wrong (or differently) in Opera (6.x, 7.x).
A couple of examples...
Subtasks view - Text and combo "subtask: # filtered subtasks: # combo go-btn" are positioned wrong (too far down).
User Management, User, Change Password - fields are not centered.
This may be something you would want to address? I know you officially only support MSIE 5.x - 6.x + Mozilla 1.1, but Opera is quite popular around techie enviroments.
