This article applies to:
This bug has been fixed in E-Prime 1.1 SP2.
Removing any object from a Procedure timeline through the workspace or Structure view and then immediately closing E-Studio does not prompt to save changes. Upon opening the .es file, the item removed remains on the Procedure timeline.
Update to E-Prime 1.1 SP2 or later.
This workaround is intended only for those who are unable to update to the version of E-Prime that contains the bug fix:
Manually save your experiment prior to removing items from a Procedure.
