Has anyone else tried using this mod with the zen-cart and gallery2 interface??

I have installed a newest version zen-cart, a newest version Gallery2, and interfaced them. That is nice, I like it so far for the most part.

The only mod I have installed on the zen-cart is this one, hoping that the photographer can hide the private events from the main page, but share a URL so people can view their wedding pics, etc... it seemed like a good plan - LOL I have the mod on another cart so am familiar with it (it works PERFECTLY there, BTW) and am sure it has been installed/configured correctly.

I suppose the interface between the cart and gallery somehow makes the 'hide' ineffective, though it appears to work in the category edit - icons update, etc...
Can it be that the categories are actually virtual folders and they will not respond to this mod?

If anyone HAS been able to get this to work please let me know so I can continue troubleshooting. For now, I have to assume it is a limitation of the merge.
