"Zend Timeout Window" crashed due to an Access Violation. -- Any ideas?

Hi there!, I've been testing some code for a company and I'm encountering something which I've never found before, right after making a call to a simple DB abstraction class which basically just makes a call to odbc_connect, then odbc_do, and then loops through the data saving the value of any field which is inside a passed array. Every time it access's this class, Norton crashguard pops up with the following: "'Zend Timeout Window' crashed due to an Access Violation." "Zend Timeout Window" is hidden, and I assume only exists for the lifetime of a PHP interpreter request. Does anyone know of a documented or undocumented problem using odbc_* under windows that causes the underlying Zend system to croak? TIA, Dw. Sqlcoders.com Dynamic data driven web solutions
