Attached is a screenshot showing what happens if all of the scripts are removed with the - button on the scripts page. The last script to exist remains in the script editor and can be manipulated. Pressing compile will always return compile successful, as the visible script is not sent to the unit. As soon as the + button is hit to create a new script, it is gone.

mbowdich,

This bug has been captured in our bug tracking system against 2.2. This should not be an issue in 2.3.

Thanks!
