When you try to log off a Windows Vista-based computer, you may receive the following error message:

AtBroker.exe - Application error
The application failed to initialize properly (0xc0000142).
Click OK to terminate the application.

Additionally, you may hear a “ding” sound.

Notes

• The “ding” sound implies a system error.
• The error message and the “ding” sound automatically disappear after several seconds. Then, the logoff process continues.
• This problem is more likely to occur when you use a program that runs on the secure desktop of Windows Vista. For example, you use screen magnifier software or a screen reader program.
