------- Additional Comments From felix.nawothnig@t-online.de 2005-11-05 03:19 ------- And there is another minor issue: dragging the scrollbar-thumb causes it to being painted at the old position on mouse-up (and immediate repainted at the new position).
I submitted a patch for that which was also rejected - but considering that from seeing that code I concluded that this glitch would happen for all scrollbars, which is not the case (I should have really checked that, yea), it would have probably just hidden another bug.
I will investigate this issue again.
