Naw, Spaw, that's not the one.  [That's the one I get when my Microsoft programs decide to do battle to the death with non Microsoft ones.]

Sarge, some of the computers on which I've had this problem get subjected to "Spring Cleaning" PRN.  Usually I get this message at a time when my internet connection is just plain being slow on everything or at a time when mudcat is especially busy [as Gargoyle suggests.]   Problem is, of course, that the browser tells me a connection was not made when, as I later learn, it obviously was.
