Hmm, it works fine in IE. I thought IE was regarded as evil and prone to bugginess. I may revert to it for the time being.
I wonder if I upset Firefox by asking it to instal Skype so that my daughter in Durham can see the cats in London.
Edit: aha, I told Firefox to go away, clean itself up, and come back. All tickety boo, it seems.
As you were...
