It is not consistant but Designer (version 2.0.0 build 337) crashes often.
TypeError: null is not an object.
This message is shown every time Designer 2.0 crashes. No other errors shown.
The application is trashed as extraneous code is inserted but ignored if you select "Ignore".
"Exit" and "Restart" mean you just loose all changes since the last save.
It may be possible to use the application if you save after every action because when it crashes it is messed up.
I know this is just a Beta but really.
Is anyone else having these errors or is this just me? At the moment I'm thinking I could code something faster by hand.
