This being your first post: Welcome to the Forums.
That said, it might be better you do not expect people here to have crystal balls. And thus nobody else on the Forums knows what you have there or are doing. Please provide them at least with some basic information like: what openSUSE level, what desktop environment, change theme from what to what. In short anything that might be usefull to give you the help you need.
Actually the information given here by kraxi is enough.
Neither Dekorator nor Emerald (Compiz’ window manager) do change entire themes, they really just switch the window decoration and nothing else.
It’s normal behaviour.
