Conflict with Next Gen Gallery and WP-shopping Cart

When I was setting up my friend’s new site I installed Next Gen Gallery.
Then she needed to be able to sell stuff so I installed WP Shopping Cart.
Then the madness began!
Thumbnails were doing cartwheels and somersaults or not opening at all.Or double images were appearing for each thumbnail.Was it a Poltergeist? A Gremlin? Nope: just 2 copies of scripts doing things together and doubling up everything! Not good.

Why was this happening?

Both plugins use thickbox.js,thickbox.css and lightbox.css.You only need one copy of each installed or you will experience odd performances of the lightbox window when clicking on a thumbnail image either on your shop or gallery pages.

My solution is probably not the best but it worked.
I went to wp-content/plugins and opened the wp-shoppingcart folder.I found thickbox js and css and also lightbox.css and just erased the code from all files,leaving the blank file in the folder.
I thought about deleting these files but then I decided to be on the relatively safe side I’d just leave them but empty.
I should say that separately both plugins work fine,at least when it comes to using the lightbox window).
Problem Resolved.
I should state just for the sake of the easily befuddled that if you do not have both plugins but are still experiencing trouble this solution will not work for you.This is just for trouble had when BOTH plugins are installed into one WP installation!
