E-Prime version 2.0 Production Release (126.96.36.199) does not contain an Experiment Advisor module to check for the use of the ClearAfter property for MovieDisplay objects.
The ClearAfter property is maintained in E-Prime 2.0 for legacy reasons only; it is not the recommended method of clearing the screen. In E-Prime 2.0 it is more effective to create a blank TextDisplay object and use that to clear the screen (see INFO: ClearAfter not recommended). The Experiment Advisor feature introduced in E-Prime 2.0 Production Release (version 188.8.131.52) Professional edition (see FEATURE: Experiment Advisor (root feature)) checks for the use of ClearAfter for all E-Objects with the exception of the MovieDisplay object. The Experiment Advisor's failure to check the MovieDisplay object for the use of ClearAfter has been resolved in E-Prime 2.0 SP1.
Update to E-Prime 2.0 SP1 (version 184.108.40.2063) or later
This workaround is only intended for those who are unable to update to the version of E-Prime that contains the bug fix:
Manually check for the use of the ClearAfter property on MovieDisplay objects in E-Studio.
