Hi.
Since Cubase 8.5, I noticed some weird behavior :
sometimes, when I close a piano roll editor (or do anything else), I have a plugin window (which was in the background) coming sudenly forward all other windows and become active ! To put it back to background, I must first clik on it, otherwise, it remains in front, even if I touch the project window, for example.
It’s really boring : I must close all windows I don’t use at the time but I like to keep them open, to improve my workflow…
My graphic driver are up to date.
Where that issue comes from ?? 
Am I the only one ? Does any one found a solution ?
Thanks.
