the code available at: http://www.usa21.net/lisawebs_demo.php
works fine using apache-linux server on-line,
but when running on apache-XP as localhost
behaves in an undescribable manner,
try create 3 records in a row,
and then check with "showall" buton,
(try 6> times to see the differences in results)
then go to phpmyadmin and browse the table...
it seems there's a kind of buffer somewhere,
that prevent from effectively writing new records,
but still show newones in the program select.
implementation of mysql is simple, standard,
nothing special.... I'm lost in the dark (of XP)
