I knew you would say that. :-)

The trouble is that HTML 4.0 + Dynamic HTML + IE4 + Netscape (with back
buttons etc) still doesn't  quite cut the mustard as far as  GUI interfaces
are concerned. You can get some good effects if you put a lot of work in
but is not very portable or robust. I would also like my GUI interface to
have reasonable session control as well. Current browsers are very dodgy
when it comes to sessions. I do get SSL for free.  But if I use Java
applets I get the other extreme. I have to code the GUI in Java, and upload
the GUI code, and the security and encryption  classes etc  and hope it
will work on Netscape and Microsoft browsers.
