Occurs near setKeyBindings inside of javascript.inc and the corresponding function inside of keybindings.js. I noticed inside of keybindings.js that you're using an array to hash keycodes. In IE 7 (and possibly other browsers) if you want to do hashing it's better to use an object because: var a = []; a[0] = 'foo'; a[100] = 'bar'; Will result in the array being populated with nulls from 0->100. Of course, maybe you're modifying the array prototype or something like that and are working around this. I tested the following change: var _keyMap = new Array(); to var _keyMap = {}; With improved results.
