FELLOW BLOGGERS - CAN YOU HELP?

I've noticed recently that I'm having trouble going back into the comments section of one or two blogs to read follow-up remarks.  When I try, the page I'm on either freezes, or, if I do get back into the comments section, all I see is an enlarged white comments box which fills most of the page and is frozen in place.

In other words, I can leave a comment on my first visit, but I can't read it or any responses on subsequent visits - although I can leave new comments on other posts on the same blog.

Can anyone hazard a guess as to what the problem might be?

(UPDATE:  The problem now seems to have sorted itself, but I wish I knew what caused it in the first place.  Anyway, back to business as usual, I hope you'll be glad to hear.)  

24 HOUR BLACKOUT? BAH, HUMBUG!

Yup... it's an upside down world!

I notice that some sites (Wikipedia for one) made themselves unavailable for 24 hours in protest at the proposed copyright clampdown on the internet that the U.S. government are considering at the moment. Seems to me akin to going on hunger strike to protest about food restrictions - or taking a vow of silence to protest about threats to freedom of speech. Go figure.
