I have just loaded the VRay Express settings which consist of 4 palettes of icons. I moved them to the top dock. However, each time I start Rhino I get the Express tools at the top dock and at the bottom of the screen in a 2nd bar. I can turn them off by digging into my preferences, but when I restart Rhino there are at the top and bottom again. Is there a permanent way to turn them off a the bottom of the screen?
