I too recommend Firefox - was quicker than trying to sort out whatever it was with Safari, though now I am curious about it too as I have had it happen to me as well. I mess with Apples when other people have problems with them, there is one in the house that I've been known to resurrect from total catastrophe during FINALS! I have a dead iBook G4 looking pretty on a shelf in front of me...needs a keyboard and some display stuff. I want to get it working! Tip: it's not a good idea to throw your Apple down the subway stairs...
Some stuff on sites, particularly javascript, seem to have a knack for busting Safari. In the case of Daniweb it could be some scripting in the features...likely the type of stuff the site's developers would know about. Knowing that like 3% (guessing) of their browser traffic is Safari might not place it high on the list of priorities. Or maybe you need to empty a cache or something. Who knows...it's hackers! There probably is a better place to ask this question. I would imagine someone more savvy on scripting and Safari could probably tell us what it is pretty quickly. Apparently Safari does have high thresholds for design standards so it barfs on certain stuff. I am not a programmer but I have had to deal with a lot of the nightmarish crap that is their world. It sucks. This is just one small part of crap sandwich these people have to deal with every day. Hence, why I would never be a programmer!
Some say disabling javascript is the key to getting around this. There are a lot of different ways scripting could have problems in a browser. I will try to test it on my end if I can wrestle the Apple away from its loving owner! Anyways, hello Firefox!
