[Malcolm, Gary]

more from the manual:
There is a defect in PHP 4.2.3 and earlier. If you register a new session
variable by using session_register(), the entry in the global scope and the
$_SESSION entry will not reference the same value until the next
session_start(). I.e. a modification to the newly registered global variable
will not be reflected by the $_SESSION entry. This has been corrected in PHP
4.3.

> The variable 'test_var' registers, but the value 'Hello
