I've had problems in the past two days as well using IE 6. I can get the front page to load but can't access the rest of the site as it's incredibly sluggish. Clearing cookies and temporary internet files didn't help.
I'm grouchy too because I've got 12 DVDs ordered from DDD that are AWOL. They've been in transit for over a month and it usually doesn't take anywhere near that long for my stuff to arrive. In their defence, an order shipped at the same time from Amazon.com is also missing. I think a mail container has been misplaced somewhere and is probably on its way to South Africa instead of Europe.
I also couldn't access DDD all day Thursday or earlier today, but it seems fine now. I first noticed it when I was going through e-mail, and the graphics in the e-mails from DDD wouldn't even load in Eudora (while all my other HTML e-mails from other places were fine), so I tried going to the actual site, with no luck. (Neither IE or Firefox worked.)
