Well...yeah it's still buggy.  It started life as
a student project and I'm not sure if the student
is still at ETH.  Particularly there's a 
System.Trap when you click the Grow button.  For
some odd reason the System.Trap window doesn't
initially show correctly, so it seems like the
System Track has gone haywire.  Running Plugin
Oberon I can minimize/maximize the screeen and
it shows up.  Anyway, it's a "WITH guard failed"
trap.  It should be fixable.  I'll take a look
at it.

I see the trap window that comes up when you try
to access gmail.  Not sure what's causing it, but
seems to be a bug in the scanner.  There's also
a lot of javascript on the gmail login page.

Most likely.  When you "Store" a Text frame it
get's saved as a Text even if it was originally
an HTML file.  If you want to save the actual
HTML you can by first doing the command:


That's found in the HTTP.Tool.  Then you'll 
store the actual HTML and WebNavigator should
be able to handle it.

Ah.  Well, the problem is two-fold.

1) The built in System 3 browser has been behind 
the times for a LONG time.  (i.e. weak, no make
that anemic support for formatted tables.)

2) The web has moved away from being strictly
a "document" centered system to more of a
"user interface" based system.  Take "frames"
for instance.  That's not something that 
someone typically sees is a "document".  A
frame is more of a "menu for documents".

Now, one can say "I'll stay away from 'fads'
like frames and just don't use them." 
And you can do that...as long as you're the
one making the web page.

Anyway, there might be a way to "simulate"
frames using panel gadgets.  But I don't
think there's a perfect solution.  I could
be wrong though.
