I recently stumbled across an unexpected behaviour by NN4.x that I want to
share with you.
Maybe not all of you considered that it is possible to load an EXTERNAL js
file through document.write() giving as an argument a string where the
<script src...> tag is included.
Such an event must not be fired onLoad or would rewrite the document. You'd
call it from within another script tag while the document is still loading,
such as:

<script>document.write("<script
src=3D'myjs.js'></script>");document.close();</script>
</body>

Both IE and NN4 would load correctly the js file and you can invoke its
functions.
Strange thing happens when you follow the same procedure within a frameset.
Two frames, up and down. Actaully was not exactly the same code: was a
complete rewriting of the document in UP frame by a command invoked on the
DOWN frame, with:
top.up.document.write("<html><head><script
src=3D'myjs.js'></script></head><body></body></html>");top.up.document.close=
()
;

This loads in a similar way the external js in frame up; now what happens
is this: frame down will be able to execute and invoke the external js file
(written in the UP frame) functions on IE, but this time oddly enough NN4.x
will produce an error message of unrecognized object (function).
NN6 handles it correctly.
Weird, isn't it?

I want also to add, in case some of you is in touch with the netscape guys,
that NN6 still has great difficulties in resizing properly a form field
when it belongs to a class that assigns to it font family and font-weight.
If some of you has NN6 try to see what happens on NN6 to the textareas on
this document:

the exceed the right margin of the browser, overlapping the border of the
tables they were inscribed in.
Even weirder, isn't it?
