[opensuse] mailto links not on top

When I click on a mailto link on a web page the compose page opens UNDER other windows. Sometimes I can't see it at all. This is very annoying and different to how the world used to be. But I don't know what has changed, so I'm asking here first to see if anybody has any ideas. My browser is Firefox 52.1.1 My MUA is Claws Mail 3.13.2 My OS is Leap 42.2 both applications are the standard versions from the openSUSE repositories. Any help gratefully received, Cheers, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
