Hi Andreas
Aaah! that exactly explains the behaviour I was observing. As they say, a little knowledge is dangerous.
So, back to the 'drawing board'
Need to work out some other way to allow the built-in JavaScript libraries (YUI, jQuery?) to play nicely with the filter JavaScript library (JSmol, also uses jQuery).
Perhaps follow one of the options outlined in:

Thanks again Andreas
