OK. This is weird. Updated my table with a tiled 1x1 png with 80% alpha and went back to the IE6 machine. It has now stopped working. Don't know why. I hate Microsoft.
But at least PNGs are 1000000000% faster than DHTML alpha and 2x2 GIFs. =)
It looks fine on IE5, just no translucent.
I downloaded Opera too, doesn't work. Complains that the server (MS IIS, or ISS, can't remember) requested and unsuported authentication protocol.
cheers,
Jim.
