By default, the Logon window is not shown when starting subsequent applications in the same session. If you want the Logon window to always be displayed when an application is started, you can use the "/FORCELOGON" startup parameter.

An example of the Force Logon startup option follows:

"C:\Program Files\Tabs3\TABS.EXE"  /FORCELOGON

Note: Alternatively, you can force the Logon window to be displayed for subsequent system startups by holding down the Shift key when starting the subsequent application.

If an application is already running on the current computer and you attempt to start another instance of the same application, the current session will be called to the foreground. To start a second session, you must either use the "/FORCELOGON" startup parameter or hold down the Shift key while starting the subsequent application.
