I frequently encounter a problem when optimizing with the optically fabricated hologram (OFH) surface where the local optimizer or hammer optimizer will not close. I have to stop the OpticStudio process in the task manager and reopen the file. The hammer optimizer seems to be much more prone to this problem.

I will provide a toy file for examination shortly; however, I was wondering if this is a known bug or if there is a work around to prevent this behavior? I do call the HLGV operands and also the CMFV operands during optimization.
