A crash occurs when the SessionProc is deleted from an E-Prime experiment.
The SessionProc should not be deleted as it is the root object of all E-Prime experiments. However, if it happens to be deleted, then an experiment will crash when "E-Run Test" is clicked. When the experiment is reopened, the User Script will be missing, and E-Studio may exhibit some unexpected behaviors.
Do not delete the SessionProc from an experiment.
