Enhanced fill not supported in current player version

Hi all

I am using FlashCS3 and i keep having this problem when i try to export my flash file to version 7 and below. It says “Enhanced fill not supported in current player version”. (i have to export flash 7 and below.)

All im using is a normal gradient fill. And i cant turn off the following options:
Overflow: extend
Linear RGB (left it unchecked)
:puzzled:

I’ve tried searching the web but can’t find any solution. Hope the gurus here can help me out. Thank you!
