Anyone using RedBox plugin?

I'm working with the RedBox plug-in (
projects/redbox). Does anyone understand why this has some weird
behavior with select boxes in forms? It apparently hides them? I can
remove the hideSelectBoxes function, but I want to know why it is


I suspect it's due to Internet Explorer's delightful habit of
rendering select boxes on top of anything else in the page, regardless
of z index.
