I am having the same problem, have you found a solution?

My slider was working perfect this morning but now slider 1 is not showing the image, it is gray. I added an extra slider and it shows fine, the problem is with slider 1. I tried to remove it but then slider 2 doesn’t show the image (just gray). This is only happening in Firefox. In IE the sliders are not aligned, they are showing part of the other slider.
