Thanks again!

I converted from Winmerge to Beyond Compare a couple of years ago -- one of the best investments I've made!

Glad you were able to get things working... Any reason you are using such an old version of PHP?

Some addon in my 1.3.9 cart isn't compatible with php 5.3, so I'm running 5.2 until I'm done with the upgrade to 1.5.3.

Which add on is it? Most are fairly easy to upgrade to a higher php version

I'm working a similar issue. Right now, I can't change to the classic template, but I have looked at the tpl_product_info_display.php for the template, and it is using the zen_draw_form call. I've also checked html_output.php, and it includes the securityToken value.

Any suggestions on where else to look?

Oddly, it happens (most predictably) on Microsoft Edge and appears to be somehow tied to particular user accounts. I've tried various session/cookie solutions too.
