Well, I tried rewriting the focus call as:
onComplete: function() {$('editdescription').focus.defer();
Is that the right way to put it? Please remember I'm very new to all
this, and still getting my head around it.
If it is, it didn't work - in fact it stopped Firefox from working.
This is not by any means a show-stopper, so I have put it back how it
was and will put up with it until I am a lot more familiar with all
this.
Thanks
Steve
