Drop Shadow in ver 2.67

[linojr99]

I've tried using the new drop shadow feature and found I was unable to get the black shadow to appear. The white border is created but the black shadow is missing.
Is there documentation avaliable showing how to show the black color or any other color?

Could you tell me which parameters do you use?

Do you have tried on simple code like Load/DropShadow/Save??
