Rob, I got a trouble shooting question for you. Been going through the learning documentation this weekend, currently still on the first tutorial wanting to make sure I soak it all in before moving to HOL and Z, but I seem to be running into a problem with one of the commands. Every time I try to use the save_and_quit() ML command in the execution Window the whole system freezes up. There is no error being thrown, it just returns val it = (): TYPE, and then locks up. Have to either kill all the window proc id's or restart the system to get rid of them. Mostly it is restarting b/c kill sometimes will not remove them for some reason. I was working on the Peanissimo theory write up. Written it several times and get the lock up every time, any suggestions on trouble shooting?
