Mac OS X 10.5: Unable to quit running application or restart; "The application cannot be launched, -600" alert

Issue or symptom

When attempting to quit an open (running) application in Mac OS X 10.5, you may notice the application still appears in the Dock as if it is running. The application may be unresponsive.

If you try to open the application again, you may receive an alert such as this:

"The application (name) cannot be launched. -600."

...where "(name)" is the affected application's name.

If this happens, you may also not be able to shut down or restart your computer.

This can happen if an incompatible version of Intego ContentBarrier is installed.

Solution

Update to the latest version of Intego ContentBarrier.
