FooBox strange behaviour

My FooBox lightbox seems to be having a problem.

When I first click on a gallery image the light box opens and everything appears like normal. However if I try to dismiss this pop up by hitting the x in the upper or click out of the pop-up then another image is displayed.

It is possible that something else is interfering with my plug in, or that the plug-in is corrupt as I have been experimenting with many features with this plug-in and others. So I wouldn’t mind resetting the plug-in if need be.

Finally, I would like not know what features I get with the paid version?

Thanks,

Bryan
