Windows defines certain keys on the keyboard or combination of keys to mean special things.
For security and application stability reasons, E-Prime permits most special key combinations such as the Windows key, Context Menu key, Ctrl+Escape, Alt+Tab, and Ctrl+Alt+Delete to function as they normally would.
This does have the side affect that if a user accidentally or intentionally presses one of these keys or combinations that the currently running experiment to terminate.
Data collected to that point can be retrieved using the E-Recovery utility.
In situations where subjects during data collection may accidentally or intentionally press these keys and cause experiment termination to occur can use a 3rd party utility to filter out these keys and make them essentially ignored. Please contact your network administrator before using a 3rd party utility that filters keyboard responses because they some have the potential create a possible security risk (i.e. not permitting Ctrl+Alt+Delete to log into or out of a 2000/XP system). There are a number of freeware 3rd party utilities that can prevent the Windows Key and other "hot keys" from functioning. Psychology Software Tools provides an example of how to use one of these utilities but does not encourage or discourage this utility or any other utility that provides these same capabilities.
Psychology Software Tools at a later time may include special key filtering in future versions of E-Prime without the need of a 3rd party utility.

Psychology Software Tools has found a 3rd party utility that can ignore special keys when they are pressed.
After downloading and extracting the WKeyKill.zip file, you can configure what keys you would like to ignore with the WKSetup.exe program that is included in the download.
To enable the "key ignore" program, double click on the WKeyKill.exe program.
You can press the special keys prior to running the experiment to ensure they are being ignored.
Please note that although the program can configure ignoring of Ctrl+Alt+Del and Alt+Tab, these special combinations cannot be ignored.
To restore the ignored keys, simply double click on the WKeyKill.exe program again.
The application has a setting to show a message when the application is shutdown when you double click on it.
Ultimately, pressing the special keys and having them work as intended will also indicate that the application has shut down.
Please report broken links to this 3rd party application to our webmaster.
