Summary
The Laserfiche client can automatically end a session if the client window is inactive for a specified amount of time. By default, 30 seconds prior to being disconnected, you will receive a message box warning you that you have been idle and that you will be disconnected from the repository. You can edit the registry to determine how far in advance you wish to be warned of the disconnection.
More Information
Add the "IdleWarningTime" string value under the "HKEY_CURRENT_USER\Software\Laserfiche\Client\Profile\Settings" registry key.
