	<slider mold="knob"
			minpos="0.0" maxpos="100.0"
			curpos="80" step="1" width="300px" angleArc="360"

1. Select the text from "text before" to "text after"
2. drag the slider knob

while dragging the selected text is dragged as well
after releasing the mouse button the slider keeps following the mouse movement

once the problem happened the whole page can't be scrolled anymore using the mouse wheel
