PHP 4.2.0 on win2k, can't use mysql_fetch_* functions

Is there something about the php 4.2.0 windows binary (installer version) that renders the mysql_fetch_* functions useless? I installed php 4.2.0 on windows 2000 along with Apache 1.3.24 and MySQL 3.23.49, and in a script i have a simple SELECT statement. The content is in the database, the query executes successfuly, but it's as if mysql_fetch_array and mysql_fetch_row functions don't return anything. I know mysql support is built-in (as indicated on php.net) and working, because i was able to use php to insert data into the database. On that one computer i was able to recreate the problem consistently and in no situation would mysql_fetch array or _row return anything. I haven't had the opportunity to try this on any other win2k boxen, but am not having any problems in Linux or OpenBSD. Is anyone else experiencing any problems?
