GTK app's do not accept KDE system colours

openSUSE 11.3 KDE 4.5.2

GTK app’s, specifically firefox, do not accept KDE system colours despite “Apply colours to non-KDE4 applications” being set in System Settings. Ideas? TIA.

An OK work around is to create a Firefox Persona, but tabs and slider bars are still not the correct colour.

In Systemsettings - Application Appearance - GTK-style and Fonts. Set it to use Oxygen-Molecule. My FF and Gimp have the same colors using that.

Doesn’t work for me. Thanks anyway.
