I'm new at this, help making start menu transparent using windows 7 style builer 1.5

[Dmugen]

Start menu-panels-aero-top-programslist

I modified the png "StartPanelComposited__StartPanelPriv_ProgramsListImage".

but didn't work, I just want the transparency to replace the white in program list image, can someone give a png for it so I replace it.


Also not sure if sizigmargins have anything to do with, can someone explain to me the the number ofsizigmargins?

Thanks
