I cannot seem to edit a scripture once I have placed it in the schedule. Computer then just bings and have to close program down to regain computer access

 I would check the other screens (Foldback, Front Of House, etc.) to see if EW is throwing up an error screen on a different screen. Also, make sure you are using the Latest version of EW7 which is 7.4.1.9.

Also look to see if there is an error screen behind EW itself.
