I do most of my development on a Windows 7 lap top (and always patched up to date), with XAMPP 1.7.4.
On older versions of wordpress, I've had no problems using a variety of Accordion Plugins, e.g.: Accordion Shortcode, Arconix Shortcodes, Collapse-O-Matic, Content Accordion, Squelch Tabs and Accordions Shortcodes (c.f. Hintonstgeorge.org.uk, and select what's on).
In my dev environment I now have WordPress 3.5.1 and none of these plugins work! They work when I install them in the Linux environment provided by my hosting provider.
Is there a fix for this, or is it a core WordPress Bug, jQuery issue or something else? Any solutions gratefully recieved. By the way, I don't seem to be the first to have this problem - perhaps the other people with the problem are using Windows too?
