Hi Robert,

Great, thanks. We use only virtualGL 2.5.2 on our VMs so they’ll both be using the same version. It could be that 6.7 uses some sort of new feature that VirtualGL 2.5.2 can’t handle. Or it might be nothing to do with VirtualGL, we’ll see if version 3 fixes the problem. To reproduce the error, I’m opening Mantid 6.7, going to Interfaces, and selecting ISIS Reflectometry, then closing that window which crashes Mantid. Is that the right way to reproduce it?

Thanks,

Adam
