ScrollBar behavior is unlike Native Cinnabar .

Steps to reproduce:
--------------------
1) Open a terminal on Cinnabar machine. write some commands so that u have a scrollbar with a small thumb.
2) Now take the thumb to the top.
3) Click mouse in the middle of the scroll Track. And keep it pressed.
4) Observe that the Thumb starts scrolling towards the place where the mouse is clicked. And then it passes it and reaches the other end.
5) But in Java's implementtaion of the GTK LAF this is not happening. The Thumb stops at the point where the mouse is clicked.
6) Now that the thumb is at the bottom of the terminal window, Click the mouse again at the same place and keep it pressed, the thumbs moves towards top.
7) This is also not happening in Java's implementation.

I have observed that the above behavior is also happening on Solaris where the scroll bar goes to the bottom/top. But in Motif LAF implementation it remains at the place where the mouse is clicked.
