Change overlayColor in admin.php

[Arthur]

Hi , i read almost all the forums but can t find the solution:
I want to have a white box.Somewhere there info about a shadowbox.init.I can't find it.
then I search "overlay" by searching in all the files of the plugin and find it in admin.php.
i tried to change the value with.#FFF' but i still have a black bg.
how can I solve the problem?
thanks alot.
