Fixed.. (i think)
Thanks for your advice, and I almost did wipe it clean last night, but
I came across the brand new version of Safari (3.1.2) and was able to download it, after about six tries.
(It shouldn't have worked, by my estimation, since the new Firefox I downloaded the day before also
began to hang right away; it was even giving me the
'Not Found (404)-- Try Firefox!" page..
anyway, I dumped it, after i downloaded the new Safari.)
Everything works now. It's almost as fast as it used to be.
But.. Safari 3.1.2 wiped out ALL of the old bookmarks which i had, except for my home page. That's okay, I guess. I was expecting it to ask me first.
I am staying with the 'Open DNS' numbers given to me here, though. No harm in that?
So, if anyone is still following this, I think it's fixed.. by downloading firefox,
gettinng onto the internet long enough to download the newest Safari,
and then dumping the firefox. I should know soon enough if this holds.
Otherwise, I will wipe the HD and start over.
Thanks everybody!
