When you run this, scroll bar moves with the tree node you click.
How one can prevent this? let the scroll bar in the 0 position
all the time unless mouse drags the bar, itself.


I'm using MouseListener to get the x, y and the row, but due to
this moving, x, y values changes...

Any help would be nice -
