I've noticed that in Aptana 2.0 over 1.5.1 that when typing a php function, you no longer get the popup window showing the function description and it's parameters.

Does anyone know how to get this working again? As I relied on it quite heavily to remember which parameters went where. Open in PHP Manual shortcut Shift+F2 also doesn't work either, so all I can do is open my browser and keep php.net open all the time.

Are either of these features functional? I know that Open delcaration has never worked annoyingly, but I had the function popup in 1.5.1 perfectly.
