You've just run across a narrower range of micros.  The ST10F168 with it's 
STEAK ISP algorithm takes clock speed as a parameter to its commands and 
includes this note in its documentation

"Note That big difference (1,5 time) between this
value and the real CPU period may affect
the flash reliability."

I don't see it as a big deal in any case, wrap it up in a batch or script, 
heck make an icon driven script on your desktop if you insist of using a 
mouse and you're done. One minute of prep and you don't risk setting it 
wrong again.
