having to include ['prevObject'] in selectors

I don't know if it's me or what, but i'm having to include ['prevObject'] in all my selectors in order for them to work with this new update.

For example, my previous selector:

$('img.myImg').mouseover(function(){ alert('test'); });

worked before, but didn't work after the update.. i did some dallying around with some javascript print_r() function I'd found, and saw that my object was nested one-level deeper... so now, the code only works as:

$('img.myImg')['prevObject'].mouseover(function(){ alert('test'); });

Seems to be throughout the site, since I've had to do this in a number of locations to make them work. anyway, i'll tell you if i figure something out.
