internet explorer 7 - IE7 jQuery 1.9.1 issues

Question

In only IE7, the script error message shows-up in the status bar, which cripples the UI. For example, if I click on any of the anchor tags, it doesn't work. By the way, this script error location and callstack was taken using the Web Development Helper for IE7.

If I include jquery-1.9.1.min.js, in IE7 I see the following script error messages:

I used jquery 1.7.2 for IE7 and jquery 1.9.1 for all the other browsers. It works fine now. Thanks to SpYk3HH.
