Dear Zemax Community,

I'm currently working from home using Zemax ia VPN and Microsoftr Remote Desktop (RDP). Whether RDP is interrupted by a lapse in internet, or is closed manunally, Zemax enters a state of high CPU and GPU utilization in which it is completely non-responsive  to mouse or keyboard input. I must force-close and redo actions like Monte Carlo simulations. Other applications on the much faster computer located at work continue to run, and allow me to use them when I return from the RDP interruption. 

Has anyone else in this forum experienced this? And is there a known fix?

Note: I'm running Zemax OpticStudio version 20.1 with a hardkey license.
