'effects' is null or not an object

Not related to content taxonomy. I just confirmed it's happening for me with regular vocabs on nodes.

Yes, I have. I just started using FireBug Lite for IE and I see in the list of JS files that the minified effects.core and effects.drop files are there, but I seem to recall that HS is looking for the regular versions. Does that matter? Funny thing is, when I select the effect.drop file to look at in FireBug Lite, I see the script as I would expect, but when I select effects.core, it shows the code for the page itself, not the script.

Any ideas? I really appreciate the help. Web design life would be so much easier without IE!!!

Firebug Lite isn't helping. There's an error generated before it kicks in, so it doesn't catch it.

I udpated jQuery_UI to 1.6 and the latest module and it actually broke both IE7 and FF3.5. Turns out, though, I don't need jQuery_UI on the one site I'm trying to get HS to work on. So I disabled it and now HS is fine. But I have other sites where jQuery_UI is needed and would love to use HS on them. Can you confirm for me the versions of jQuery_UI that you tested? On the site status page, it says I have 1.6 installed with jQuery 1.2.6. I've tried jquery_ui module 1.3 for D6.

Until your suggestion that I upgrade, I was using 1.5.3 of jQuery_UI. With that, FF worked and IE7 was broken as I said. I wonder if something else is conflicting. Do you know anything about the following modules? Tabs, Views_tabs, cck_fieldgroups_tabs, vertical tabs. Until now, and with jQuery_UI disabled, they all work fine with your module and each other. If you don't know, I'll look elsewhere for idea. Thanks again.
