Look & Feel problem one iview differs

Hi there,

I have got a problem displaying one iview, one of the iviews in our portal uses a different background color. This color is not mentioned in the theme used within the portal.

I checked the sap.useWebDynproStyleSheet parameter in the visual administrator which is set to default (false) so all the iviews should use the portal theme.

How is it posible that this particular iview-application uses this different style. Is there some kind of override?

thanks

Ron
