The Yast2 applications have extremely poor usability as they have status indicating popups which steal constantly focus. For instance the software installer can work on a slow network connection for minutes, every once in a while making a new popup for the progress stealing the focus. This is against Gnome HIG and also extremely irritating behaviour.

On top of that they can at worst cause security problems as they steal the focus when you are ie. typing your password on an other window. (At least I browse constantly while these tools are doing their work and have ended up typing my text into the Yast2's dialogs...)

This should really not happen. No application should ever steal the focus. There's simply no excuse for it.
