This problem seems to happen when closing SU after a session using Vray. Its happened a hand full of times and I only noticed the last couple of times after doing some renders. I save the file then close as I normally do with the “X” in the upper right corner of the window. One time it seemed to not be closing so I used the file pulldown and chose exit. The issue is all of my toolbars are undocked and the tray is turned off. I doubt there is a fix until the next patch comes out and I cannot say it happens everytime I use vray. I really dont want to continue to “practice” placing the tool bars. It takes more than a minute.
In case anyone is running low!
