I found one problem. I dont know if it is bug or I something wrong setup. If It is core or commerce problem, but appear in commerce.
When I change product variation in teaser view (default hompage or created view page) using ajax to change price, image, ... An Ajax error table appear : An error occured while attempting to process /system/ajax:NPMethod called on non-NPObject. Same thing after update button in cart.

Its only in CHROME (version 31.0.1650.57 m), I choose my notebook with same version of chrome, error not appear. Both running on Windows platform. So I investigate: Found that when I disable Surfing protection in Advanced system care 7.0, error table not appear.

But in both enabled or disabled protection, in chrome console (F12) I found this warning: event.returnValue is deprecated. Please use the standard event.preventDefault() instead.
I dont know If it is the reason, but found that this warning is a jQuerry error repair in newer version 1.11, commented here http://bugs.jquery.com/ticket/14320.

I don't know what NPMethod or NPObject are, so I'm not sure this is even related to Drupal. I'd look into operating system issues and see if it's related to that. If you can reliably reproduce this within Drupal Commerce on other environments, feel free to reopen this with the steps to do so.
