I've been reading a bit about Java, and it seems a simple band-aid
would be for programmer's themselves to write such a busy signal
into their code. It wouldn't prevent the delays, but would prevent
the lack of communication.
In fact, if there are any Java programmers reading this, perhaps they
could write a generic busy signal and distribute it.
Also, I went to the page and everything clipped along just fine (8:00
am CST on a pentium 133 running Windows 95 with Netscape 3.0 gold).
I couldn't find a button for aromatics, though. Am I just blind or
does someone know of a reason it would not show up on my system?
Java works fine, but do I need to download an extension?
