[OpenLayers-Users] drag zoom control images

[R. Ortner]

I´ve exactly the same problem. When i move the slider with the mouse, the
slider stick to my cursor. When i move away from the slider and then go back
with the mouse the slider is still pending on the mousecursor and moves also
out of range.

don´t know how to fix that
