It did crash when I tried Vinicius' bug regarding the usage of UNICODE on
connection and trying a SELECT * FROM CLIENTS WHERE FIRSTNAME LIKE 'ç%'
statement. Full discussion about this is on IB-Support. I had to shutdown
Windows in order to shutdown Firebird and even then Windows had to force
Firebird's shutdown the drastic way. This only happens when connecting
with UNICODE character set. Vinicius did say that he needed it to work,
because he deals with China and I might in the next year or two.

I just written a reminder to myself.

Thanks for the remarks Helen, I'll keep them in mind and make sure for my
software distributions do make sure that it's as close to a clean install
as possible when upgrading. And, I'm always logged in as administrator,
because I'm the only one that uses the computers at my location(home-office).

Again thank you both for the explanations and time. And, again excellent
work on Firebird.

Have a nice day to you both.
