I've been meaning to post about this bug but I don't think I have.

SuSE 8.2, KDE 3.x (I forget, sorry), PgS Linux 4.1.6.13

Open document, new or otherwise. Click on the document scrollbar and move it.
The mouse pointer is free to move, but does not let go of the scrollbar.

Now, the behavior is not 100% consistent. I just tried it three times with a
new document, nothing in it. The first time it behaved fine. The second time
it clung for a little bit and let go. Curious, I tried a third time and got
the same behavior. This was at Full Page view.

Changed view to Actual Size. Definitely more clingy, but still lets go. Opened
an existing document (small, text only) and it was clingy, but still let go.

In fact, the behavior I'm producing (as opposed to remembering) is that the
final point it snaps to is where I let go of the mouse button, but there is a
time delay before that scrolling is enforced in which it tracks the mouse
movement.

The behavior I remember is that it would not let go at all until clicking
elsewhere, but I can't seem to reproduce that at all.

Possibly it seemed more like that in earlier versions where screen updates
were much much slower and that colored my uncritical observations of the
current?

At any rate, I can reproduce it "clinging" to the mouse and then snapping to
the proper position. Not major, but still a bug.
