Technical Hitch in Blogger

I think microwave transmissions have peaked, probably due to unforeseen activity in the Middle East, or solar flares, or something, and the tipping point has been reached, provoking a global wave of temporary insanity.

I offer as evidence that yesterday evening I suddenly felt compelled, for reasons I can't remember, never mind explain, to update my Blogger template.  Why?  It was perfectly OK.  Anyway, I did it, using their wonderful new 'template designer'.  I had a look.  I wasn't sure if I liked it, so I thought I'd find some kind of undo function.

This morning I started this process.  It took most of the day, but finally I managed to get back to where I'd started, except that Sitemeter had disappeared.  Fair enough, reinstall it.  So I followed the instructions, meticulously.  They involve pasting HTML code into the appropriate place then saving the template. 

I've already bored you into submission, so suffice to say that eventually I discovered that Blogger have just introduced a new feature (old IT-speak for F-up) that, as I type, makes it impossible to save HTML.  They are silent on the subject, though hundreds of people have posted complaints.. 

I can't think of any reason at all why they'd do that, change a basic function that worked perfectly.  Or why they seem incapable of backing out the change.  Temporary mass insanity seems like the only answer.  Other examples spring to mind.
