the colour fx are the same as the layer ones- some of them dont do anything useful - or will display nothing-

some of them also have transparency.

The LFG card and the mac sometimes have initialisation issues-
i have used the application 'expansion slot utility' to reset the pci express card bandwidth settings to clear this up in the past.
this is hidden away in System->Library->CoreServices->Expansion slot Utility

this is the program you see when you insert a new pci card.
