Today I downloaded and tested the beta 14 with Cecilia's 261 MB super-shed file.
Using beta 11, I was able to make a photo render. Using beta 14 my computer stops rendering with the infamous red cross. Also, when trying to move the virtual my computer freezes. It also freezes when I try to use a separate window for the 3D image. All of these were possible with beta 11.

It looks as if memory management changed...?
For the time being I will revert to beta 11.
