I've been experimenting with loading some jQuery plugins and noticed that when adding these .js files to my .info file, it messes up the normal function of jquery on my website. My plugin functions works . . . but then I noticed that when I went to do some work in Rules, the selectors were missing or something and the little blue ajax spinner or whatever it is would spin for a second then stop but nothing would load. If I comment out my new jquery script loads from .info, then all works well again.
I suspect I'm loading jquery files that are displacing the standard jquery files I need on the site (I'm using jQuery Update module).
I got my jQuery files just form the jQuery UI site and I'm loading all three, including jquery-1.9.0.js
What might I be doing wrong? Too many questions perhaps.
These are the files I loaded from jQuery UI:
;scripts[] = js/jquery-1.9.0.js
;scripts[] = js/jquery-ui-1.10.0.custom.js
;scripts[] = js/jquery-ui-1.10.0.custom.min.js
;scripts[] = js/custom.js
I commented them out you see.
I can get more specific if anyone has time to answer, but I thought I'd see if there was some general advice or an easy answer.

Jquery update module includes
Jquery update module includes a version of jquery. Depending on what rev you installed you will have a newer version. So you shouldn't include jquery again in your theme. Plus you are including two jquery_ui instances. One is minified (I would keep just that one).
Some additional suggestions would be to try and only include js on the pages you need it. You can use a template preprocess function in your template.php file for that.
Hope that helps.

There is some sort of
There is some sort of conflict with recent versions of jQuery with some contrib modules. To use jQuery beyond 1.6 and ui beyond 1.8, it seems we need to wait for D8.
