After crashing Netscrape (4.07), the next time I tried it, it worked just fine.

My question for you: why are you using an ilayer? I assume you are intending to do DHTML stuff with it... If not, just use <div> or <span> to get your W3C-compliant attributes set.

I am currently involved in a HEAVILY DHTML-ized website for a promotional materials/printing company in Fort Smith, AR. Having dealt wit DHTML in Netscrape and Exploder, I have to say, "I hate Netscape!" Exploder has its problems, but for DHTML it is basically just downright nice... Standardization will help tremendously, of course.

Anyway, back to the issue at hand...;-)
"Layers in tables" has always been a shaky proposition, at best, in Netscrape. Our experience says you *must* use <layer> (or <ilayer>) calls to have any hope of it working, and even then, good luck.
