Comment 11 for bug 371618

It's more than calculations and such; I've encountered a document that has a "helpscreen" overlay that you are supposed to click on to make the box go away when you're done reading it. But since it is apparently using javascript to do it, you cannot get rid of the box, which covers a majority of the page, and tehrefore cannot fill out the fields. So no, not an enhancement, definitely a bug, since the document is completely unusable without the JS support.
