I just upgraded to the 2.9 version and had to modify my existing sliders because of some different behaviors with the height. Every time you correct one layer that wasn’t working another layer gets corrupted. For example, I notice a font being small, so I replace it with a large font and a different color and it’s fine, but then, perhaps a box layer won’t appear, so I fix it by recreating the same exact thing, and so on, and I get caught in a loop of fixing. I turned off query update module, and nothing, then I configured it to 1.8 same thing. Currently the module is on with the jquery configured to 1.7.
