[wp-hackers] 2.8, add_submenu_page and class functions

[Chris Jean]

I don't see any problems with the code itself. The problem could be due 
to another problem in the code elsewhere. Would you be able to send a 
failing version of the code my way for me to test?

FYI: I recommend that you use the form of "array( &$this, 'function' )" 
when passing an object's function. Passing $this by reference allows 
PHP4 to play nicely. Otherwise, you'll run into really odd issues on PHP4.
