With jQuery 1.4.1 I'm not able to track when change event occurs for file inputs (i.e when you selected file and closed file dialog). It occurs only when I'm clicking on file input once again.

1.3.2 doesn't have such bug.

I guess, problem is somewhere below this:

// change delegation, happens here so we have bind.
if ( !jQuery.support.changeBubbles ) {

At least, when I replacing

var formElems = /textarea|input|select/i;

with

var formElems = /textarea|select/i;

it works like a charm.
