If the page is longer, and the scrollbar appears, the innerWidth is still reported as the size of the entire browser. I worked around it by comparing the document.body.offsetHeight to the innerHeight to see if the scrollbar would be present, and changed the innerWidth according to that. Reproducible: Always Steps to Reproduce: 1.Create a page that displays the innerWidth in javascript without scrollbars 2.Make the page longer so the scrollbar appears, innerWidth will be the same value (this is wrong) Expected Results: It would make more sense for innerWidth to return the available space (window size minus scrollbar width)

Does IE have innerWidth? If not, this is invalid, since innerWidth in NS4 does not account for the scrollbar and we only have the property for NS4 compat. You may want to just use document.body.offsetWidth.....

Just checked and IE does not support window.innerWidth... so our behavior is correct as far as NS4 compat goes.
