Eric there is no official support for the plugin in those forums (I had wandered around in there a bit before sending them my help request — via their support form). They literally told me “the support forums are gone”, and sent me a link to this forum. Is what it is I guess. Really shocking to me given the reputation StudioPress has WRT to customer support and paying attention to details. Seems this is one detail they don’t care about enough to have a dedicated wiki and support forum for their plugins that is easy to find.
The search of that General forum reveals several Slider threads, most of which have no answers in them. I’ll dig around the CSS I guess.
