Thank you. I tried this. It made the window bigger but not the workspace. When I opened the config file again to try some larger numbers, I found that something (the OS?) had changed the WindowWidth to 1512 and the WindowHeight to 851. The meow numbers did not change. I think you may be right about it being a mac OS issue, but not sure where to go from here. Is there a way to call attention to this question so that knowledgable mac folks are likely to see it?
