This is great.
I tried it for the first time earlier this week. Saw the update so tried again w/the latest Beta.
I did see a problem - try using an object with a lot of properties in the command window - like _screen.visible. In the command window, it works.
Then create a new program (or add to a method or any other program entry type of screen). Enter in the same _screen.visible. The VFP design environment hangs.
Same if you use a self created object with a lot of properties.
