This bug is very easy to reproduce. I have personally verified it exists in IE 7 and 8.

I have this simple select:

<select name="zlecenia_index_icpp" id="items_per_page">

<option value="10">10</option>

<option value="25" selected="selected">25</option>

<option value="50">50</option>

</select>

and the following code is used for the change event:

$('#items_per_page').change(function(){

var controller_action = this.name.replace(/_/g, '/');

location.href = config.base_url + '/' + controller_action + '/'+this.value;

});

This code used to work in jQuery 1.3, but in 1.4 the change event is fired as soon as I click on the select box. This only happens one time and then functions normally.

I can't verify the actual problem but it works alot like this code:

$('#items_per_page').one("focus", function() { ... });

Here is where it was originally reported, or at least where I saw a confirmation that others were experiencing my same issue.
