For some time now i've been trying to fix my site for Internet Explorer, so that it'll work in at least IE8. I'm using a custom jQuery script to "handle" my whole site, but IE isn't playing along at all. To start things of, it seems to ignore some commands - resulting in all my projects showing from the start. If I try to navigate my menu, I get some cryptic error telling me "Invalid procedure call or argument" in the jQuery file itself. If someone out there knows what's going on here, I would be incredibly grateful for any input on how to fix this because I've ran out of ideas and things to Google.
