In the attached test case, there is an internal frame
that contains a scroll pane. Just like in native
Windows applications, it should be possible to click
on one of the scrollbar knobs and immediately start
dragging it even if the internal frame was not
activated/selected before the click occurred.
At the moment, two mouse clicks are required:
one to activate the internal frame and another
(separate) one to move the scrollbar knob.
This is annoying.
(Using the arrow buttons works, though.)
