Can you post a test-case to duplicate the problem?

setAuto was removed from jQuery core. Maybe this helps to fix it:

I just want to do a sanity check, because I've never delved into any of the
interface code (ifx.js)

I'm using Thickbox, and added some custom code to use the "BlindDown"
function on one of the animations (from the Interface plugin).  Everything
comes up fine, however when I tried to close the Thickbox the box went away,
but the opaque overlay didn't, and I got this error:

jQuery.setAuto is not a function (ifx.js - line 147)

I went into the ifx.js file and commented out the following lines:

// set its height and/or width to auto
//if ( p == 'height' || p == 'width' )
//	jQuery.setAuto( z.el, p );

Re-ran and everthing worked great.  I don't know enough about the changes in
1.0.4 to know *why* I had to do this - but I just wanted to see if it made
sense to anyone.

Thanks,
Chad

Comment out those lines will caused some wierd behavior to elements that has been hidden (their property somehow can't be reset)in IE, it seems to work fine in firefox

I simply add to interface.js file a line with the following:

$.setAuto = function () {};

It seems to work well.
