Split Screen not working

I am using Resolve Lite on 3.2 GHz Intel Core i5 Macs running OS X 10.8.5, GeForce GTX 675MX 1024MB, and CUDA version 5.5.47. When I try to do a split screen half the image just goes black. This, by the way, is the same for all 30 computers in my classroom. Any ideas what might be wrong?

I presume you are talking about the gallery split screen. Check the first configured volume in "Preferences". The stills are saved there under a .gallery folder. Most probably the user account you are using doesn't have write permission in that folder.
