Sorry Bob, After almost a month the problem is now gone. This has been a Post hoc ergo propter hoc confusion. This AJAX routine broke after a number of changes. My initial target was that it was the result of a SAN controller emergency that my provider had to deal with for a block of users. We were down for half a day. I talked to them after the fix, and they insisted that my problem just had to be a cross domain browser issue - not server issue. Now I’m thinking that there was a problem that was subsequently fixed. I have to write to them. They’re probably not going to believe it, and I don’t understand it either. Why would a page server create a problem with a client side AJAX call to PubChem? But here’s a fact. It was not broken at ISU - just CheMagic.
Anyway, the browsers I track seem to be happy with the PubChem routine again.
