first i would like to thanks the ASGVIS team for their work even if i want some more !
second, i think there is a problem on foreign version of rhino with vray.
at start the layout is reseted on a default like version.
the tool on the left side are removed exepted the two first rows.
this odd layout is present since rc1.
I just figured this one out last night actually. It turns out that calling “_exit” does not handle saving the final layout of toolbars. And currently VRay for Rhino intercepts the closing of the Rhino window and calls “_exit”. So I’ve changed that, so this will be all fixed in RC2.
