Godfrey, in a nutshell you're telling me, that my K10D is perfectly normal and that except, may be cleaning (last cleaned by local service almost a year ago), it requires no special attention at all.
That's what I've been thinking but this is the very first time since 2002 (when I bought my first AF film body by Pentax) the AF of any camera I ever held in my hands behaved that strangely. In fact, my simple ZX-L (MZ-6) still works perfectly well in all regards, including AF. Which liquid I could use to clean the mount contacts on the body? Perhaps it is time I cleaned the mount properly?! Generally I don't hmmm treat my gear any specially. I try not to abuse it but that's about as far as it gets. Cheers.
