Well, I have now downloaded Combo Update 10.10.2, backed up everything, 
repaired permissions, verified Disk. Repair Disk returned ‘OK’. So I then 
installed the Combo Update. It only took a few minutes, and, sadly, I still get 
blank pages when I use Quicklook on .html files.

Bare Bones asked me to run mdls on Terminal and send them the result, which I 
did. Haven’t heard back from them yet.

I suppose I will submit a bug report to Apple. If only some people experience 
this problem, is it possible it is because their computers are a particular 
model?

Thanks to all,
Pat
