Re: amaya and thot up and running on FreeBSD-3.0

Hi,

Yes, I am using the Java version.

I noticed that in init.c:LoadHTMLDocument, amaya gets a little confused
with respect to determining if the cache directory is created or not.
Not sure how to fix it  however I would do a stat on the cache directory
and if it is not there create one. The symptom is that amaya fails
to display http:// urls however local files are displayed with no
problems.



Going back and forth with sites , I managed to get this core dump:

ine 2055, char 104: Unexpected end tag </FONT>

Not sure if you are interested on the dump given that is already known
that there are synchronization problems.

On a different topic, and the one I am really interested on is why 
Thot was not originally designed with SGML in mind?

This is what one of the FreeBSD hackers had to say:
