This bug has been fixed in E-Prime 1.2 (184.108.40.2062).
When accessing ResponseData values returned by the InputHistoryManager ( e.g. Keyboard.History(x) ), an unexpected runtime error occurs.
Upgrade to E-Prime 220.127.116.112 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:
Device.History.RemoveAll at the start of an experiment.
