@donn (or whoever): I understand that I am doing things in an unorthodox manner by running both OpenROAD and openlane (and yosys, and klayout, and. . . ) natively on my computer. However, I'm hoping you might have insight into this issue: Whenever openlane calls klayout to do some job like generate GDS, klayout keeps popping up a GUI window on my desktop. It's like it refuses to run in batch mode. It's in its default state when it comes up, and appears not to have noticed that it was passed any arguments. Ever come across anything like that before?
