Let me be clear, the developers of this plugin did a great job... it is easy to use and looks great. If you consider the cost (approximately zero) it's amazing they they give as much support as they do through their forums.
They should however manage the expectations of people using it by being up front about this problem: it will not work if you have one or many other popular plug-ins installed (Lightbox for example) There is no work around to this. If you happened to have bought a theme from studiopress that has a hardcoded reference to this plugin you have more reason to be angry at studiopress.
It is not impossible for multiple plug-ins to share libraries, so I hope that this is eventually cured.
