Is there a reason things would not be displaying under jQuery UI?
===

I have a single-page application that is meant to display certain information when people click on a jQuery UI accordion to the left. If I set an initial "display: none" in the CSS for a page or call jQuery(selector).hide(), it seems not to be showable after that point, at least not using jQuery(selector).show(). Debugging statements confirm that the selector it is using is in fact the one intended, but nothing shows.

What am I doing that neutralizes jQuery's ability to show() a DIV?

TIA,
