Thanks, always good to know that it's just finger trouble, rather than overt action!
PS: I've been a member here for many years, but similar finger trouble seems to have done something obscure to my original account. I've been assured via a back channel that it's definitely not moderator or admin action, or anything I've done, just one of those glitches that can happen from time to time with any bit of software. Bit like my new-ish car, the software in that behaves like that in some aircraft, and my wife tells me that my response is the same as that oft-heard CVR phrase "Why the hell has it just done that?"
