ZC version 1.5.3 - fresh install via FTP and zc_install
I've installed the Responsive Classic template (http://www.zen-cart.com/downloads.php?do=file&id=1816)

The popup resizes just fine with the regular green template, but not with the Responsive Classic template selected, so I know it's something with the template. I'll be darned if I can figure it out though. The popup has the image at the correct height, but the width is always 116 pixels. I've done a search using the Developers Tool Kit and can't find a reference to 116px anywhere. I'll probably figure it out as soon as I post this, but if not, could someone give me a hint as to where to look to find the problem? Thanks! :)
