I used this module combined with the Better Exposed Filters module to turn multiple selects into checkboxes.
When I tested in IE it wasn't working. I had a look at the JS file at views_hacks/views_filters_autosubmit/views_filters_autosubmit.js and found that the form was submitting on the change() event for the form elements.
change() does not work on checkboxes - http://api.jquery.com/change/
The change event is sent to an element when its value changes. This event is limited to elements, boxes and elements.
So I had to modify this file and use bind('click change') to cover both scenarios.
Attached is a patch
