Q9. I have the right version Flash Player/Plugin, why doesn't my movie work?

A. You need to increase the memory allocated to the application.

This is only relevant to OS 9 and previous users, OS X dynamically allocates memory.

Select the application that is running the flash movie (e.g. Flash Player, Internet Explorer etc.) in the Finder.
Go to the File menu and choose "Get Info".
An information window for the selected application appears, choose memory from the dropdown menu.
Increase the "Preferred Size" box by 1000.
e.g. 800KB --> 1800KB
Depending on the size of your movie, it may need more, but keep the order of magnitude you increase by in the thousands initially.
