[Plugin: jQuery Lightbox] problem with iexplorer 7 [upgrade to 0.6]

hello
I’m a big fan of this plugin, but … when I upgrade all the images crash the pages when use Iexplorer 7.

A little box with some text appears in top right in the page [!?]

I re-install version 0.5 … for now, at least
all the best
