Title: VE-247: Prevent window from scrolling for Internet Explorer

Setting focus on input elements causes Internet Explorer to scroll unexpectedly.

jquery.focusNoScroll.js
This jQuery plugin captures the window scroll position, calls focus(), then sets the window scroll position. This is chainable and is a direct drop-in replacement for focus().
