@eugene-d  - no :-).  Currently, if the user starts dragging the slider whilst in a tour, the tour disappears, and re-appears when the slider is released.  I don't think the tour should re-appear.  

To me, when the user starts to drag the slider he is mentally thinking "I wish to finish the tour, and look at things myself".  So, we should finish/complete/terminate the tour when the slider moves.
