Problem with JQuery, TextArea and Firefox

Problem with JQuery, TextArea and Firefox

Hi there,

I can't work out if this is a bug in firefox, jquery or my code. It is probably the latter but you never know...

My code is supposed to update the text in a textarea based on the value selected in an option list. It works perfectly in IE7 and it seems to work in FF 3 - until you make an edit to the text in the textarea at which point it simply ceases to work with no errors reported.

Check it out here...

Has anyone else come across this problem and found a fix?

Thanks in advance
