I'm installing Zen Lightbox v1.5 on test site 1.3.9d. Didn't install IH2.

On tpl_modules_main_product_image.php I've got two instances of:
. addslashes(TEXT_CLICK_TO_ENLARGE) . in my existing file that are shown as" . TEXT_CLICK_TO_ENLARGE . in the mod file.

Both files appear to work. I'm not sure where the addslashes came from in my existing file, copied from custom template in livesite. I have same lightbox on livesite zc 1.3.8a also with IH2

I don't see the addslashes in Lightbox files, or any zc clean files.

Anyone know what gives?
