If you use the Web-FX IE emulation code and users hit your site with Firefox 1.03… it’s not going to work. I don’t fully know what happened in the Firefox code but you can replace all instances of ‘this.[javascript object or parameter]’ within the extendEventObject function. Due to not being certain of legalities that are involved in posting corrections of others work I’m not going to include the corrected file. This library of code is also used in the coolbars2 code so you’ll need these changes for that as well. By my testing the changes are backward compatible to older versions of Firefox and Mozilla.

Hope this helps others, because it freaked me out 🙂
