I just went through a few hours setting up an OpenSIM server to run locally on my laptop. I have had problems in the past getting this software to work, or have crashing issues. Tonight, everything was practically perfect. I was able to log in, change my appearance, modify the land and make a building with a court yard. I even made a few scripted objects. Not once did the software crash on me. I do have problems with trying to enable physics (or determining if it is available yet). For now, I’ve risen the land to be just below the floor of my building.
