I am running .56 and the slider tooltips do not show up for me if the slider is moved from its original position.
if i move the slider at all they are gone until i move it back to its original position then they show up again.
Mike - I have the same issue. However, if I move the slider back to the original position the tooltips are shown.
The tooltips are disabled while the bar is sliding. When the slider stops moving, your cursor is most likely going to be pointing at one of the slider images. The tooltip for that image should have popped up when you pointed at it, but the bar was moving at the time so the tooltip was cancelled. If you move your cursor to the image to the right or left, you should see the tooltip popup again – or move the cursor away from the current image and move it back again.
