Hi Greg,
When I place an RS Renderview in the lower left corner, save that Layout as RS View, then move that RS Render View to the upper right corner, and save it as RS View 2, then it stays there.
BUT: not when I go from RS View directly to RS View 2, only when I use a different Layout in between. I change the RS view two by scaling the RS Render smaller.
Then, I save the layout, but I have to go to another layout for a moment, as the hardwired rule (AFAIK) seems to be that the last window appearance sticks, so I have to go out and then to the desired one with the same windows.
I have no idea how to overcome this.
Perhaps check with tech support. Admittedly, even if I like to have things differently, I need to stay in the standard layout as a trainer. Hence, this is not an area where I have a lot of muscle memory.
All the best
