Question

I have a button that checks all checkboxes in a div and un-checks.

However if I were to manually check one checkbox, then hit the Check all button and then uncheck all, the checkbox which was manually checked does not become unchecked!

Any ideas?

Thats because jQuery was changed in 1.6

Using attr instead of prop is what is breaking it.

Try using prop instead
