[wp-hackers] updating plugin admin menus on the fly

[Callum Macdonald]

How are your options being updated? By your own code, or by options.php? 
If it's by options.php then your browser is redirected back to the 
options page and the options are saved simultaneously. So you might 
arrive back before the options have updated.

Otherwise, you could hook your update_options() code into the action 
'init' so it runs ahead of everything else. Then by the time the rest of 
your plugin code runs, your options should have updated already.

Cheers - Callum.
