You did say that IE "doesn't read JavaScript," which is not true regardless
of the extent.

I do understand your reluctance, especially given your client base. I write
JavaScript that must work with IE 3.x, Netscape 3.x, and also on a Win3.1
platform. It's not easy. But learning the object/event models supported by
each of these browsers allowed me to quickly rule out the few unsupported
objects/events in each.

Overall, I have found that IE 4.0 interprets JavaScript better than Netscape
4.0. For one thing, objects in an HTML page are global rather than local,
making the code easier to write. This means I don't have to explicitly pass
the object around from function to function as a parm. With Netscape, this
doesn't work. Now you could argue that IE violates strict encapsulation, and
I couldn't disagree with you on that point.

BTW, if you get a chance to browser one of Microsoft's web sites, view the
source and note the usage of language="javascript" in their scripting. You
might be surprised (as I was) at how prevalent it is.

Regards...Kris
