Hi ,
sometimes the render setup panel (vray panel) is on the screen but I can't click on it,I have to close the panel by the icon on the bar and then reactive it by click render panel on Sbr panel .
When the panel is "ghosted" is still on the screen ,when I pass over it with another window it disappears where the window pass over .
I have a double scrren and the render panel is on the secondary monitor .
