plug-in editor "always on top" Not working on Window7 x64

Hello,

plug-in editor “always on top” Not working on Window7 x64

I have Cubase 8 installed on Windows 7 x64
I have deselected plug-in editor “always on top” in the Preference under VST - Plug-ins
But every time i open a plug-in it stays on top, and the plug-in has “always on top” selected
