Frozen Inputs On Some Products

I just got some feedback from a customer on a glitch in our cart. On some products but not others, as soon as the first option is selected, a small black box appears in the middle of the screen. It looks like the box that would normally have the wheel indicating its processing the input. It doesn't disappear and locks any further mouse clicks. It happens in Firefox & Internet Explorer but not Chrome.

I would attach an screen shot except I can't find the button here to attach it.

If you are familiar with the developer console in your browser, please check ajax request response and errors in console

Problem solved - by CS tech support. It turned out to be a bad line in the .htaccess file. A Redirect 301 that was blocking the cloudzoom.js and the cart access.

Thank you for keeping us updated
