Thanks very much - that seems to have solved it. I use Privoxy too. I had 
to toggle that setting on, even though I had disabled Privoxy, and excluded 
the problem sites from proxying, to try and figure things out. I thought 
those measures would get Privoxy sufficiently out of the loop but that 
switch does something. Now I can put everything back.

Yes, I was getting a bit crabby when I asked that. There does seem to be 
progress and Konq is still my default browser after all these years and 
other alternatives. WebKit seems to be (more) useful for eBay now so that's 
a positive benchmark for me. 

Thanks again - you saved me tons of grief.
