Only if you're using Java in the browser.

Seriously, though, you've obviously not used OWB on an AmigaOS 4 machine like mine (604e @ 200Mhz A4000 Voodoo III etc.) I was reading BBC news on it just this morning, and it rendered pretty much exactly like a PC browser.
Yeah, IBrowse and AWeb are less featured, but I find them much more responsive than most PC browsers because they're built for low-resource machines. I use AWeb usually under OS3.9 and OS4 because it's faster, but as soon as a site needs CSS or something heavier I go to OWB.
Compared to a 486... well... I know which I'd rather use. Maybe I should fire up my DX2/66 and compare. It's got Netscape 3 on it, that should suffice. Actually, NS3 is a lot less compatible than AWeb, so I'd need to install Win95. Which is a dog on a 486, so maybe I shan't bother.
Really does sound like you have a problem somewhere with your Amiga though... because you seem to be the only person on here who is having trouble with it!
You did see that YouTube video of an A4000 running OWB didn't you?
