If I run this command, after entering my password, all I see is a shortly blinking new `cmd` window, then nothing.

    runas /user:<username> batch_file.bat

My batch file contains a `pause` command which should therefore require me to press <kbd>Enter</kbd>, and so I would at least expect the `cmd` window to persist until that point in my batch file.

Am I doing anything wrong? How can this be fixed?
