I’ve recently updated my jquery to 1.8.0, and since doing this I’ve found a couple of errors on IE 8, when loading the page it works fine, although once clicking on say the “showreel” link up the top of my page, it returns an error saying “not implemented”.

I’ve go no idea what It’s winging about saying it’s not implemented though! Has anyone ran into this problem before?

The particular error you are seeing is discussed here http://code.google.com/p/simplemodal/issues/detail?id=7. It sounds like it’s an issue with using the dialog code in IE8 in standards mode. There is a work-around suggested in that discussion thread – you’d have to see if that applies to your code.
