We've come a long way. Remember those fierce arguments over making the Zone work with that crappy old Navigator 4? Aiiiieeeee!
The present design works with browsers that conform to the international tech standards (W3C). I'm taking the high ground, in other words. Within the category of compliant browsers, Preview is the only feature not available on the Mozilla family of browsers (FireFox et al). I need to fix that and make Preview available on both browsers, since later versions of FireFox should be able to handle it.
I've come around to the view that the technical standards are vitally important to making the entire Web work; this is about more than just what makes my life easier. If I don't bend over backwards (and waste huge amounts of effort) to accommodate oddball and obsolete browsers, I contribute to the pressure that the users will put on companies like Apple and Opera, to get with the program and conform to the standards.
At my last big on-site consulting gig, the client was spending millions of dollars to accommodate any and every Web browser that anybody on Earth might possibly be using. I suspect that in some cases, the oldest and weirdest browsers, they spent thousands of dollars per user, and that's just plain nuts. Worse, the resulting Web site was pretty much a least-common-denominator affair, and nobody was served well by it. Their good intentions had the pathological result of miring them in obsolete Web standards, and good intentions like that hold back the entire Web.
I'm sticking with the standards, and letting everybody else play catch-up.
