This happens to me periodically.
Load FX Chain preset gets me a completely empty dialog now.
It could be any dialog in Cubase really.
Shortly after that Cubase crashes. Next time I restart Cubase, the glitch is gone.
Anyone else seeing this? Its making me insane. I have not paid to upgrade 10.0 pro to 10.5 because I heard 10.5 is buggier than May and June in Alaska.
