Vst plugins always on top even though unchecked from prefs

I have unchecked the setting from preferences : plugin editors always on top

Yet everytime they are on top unless i click the spesific plugin window gui and unselect it from the dropdown menu. Load the plugin again and there it is checked. Not a big deal but it manifests itself on behaviour such as kontakt “popup question window” staying under the plugin. When such windows appear , i have hard time clicking yes or no to the questions and the whole thing is locked until answered. Anyone else having this trouble?

Starting empty project or anything doesnt remove the behaviour

In on windows 7 64bit sp1 , cubase pro8

I have exactly same problem

Any idea from anyone?
