22 | * |
23 | * As of 2.1 we have only two buttons: Login and Cancel. | |
24 | * | |
25 | * If you hit Login then a login is attempted. If it works the window | |
26 | * disappears and the settings are saved, otherwise they are NOT saved and the | |
27 | * window remains. | |
28 | * | |
29 | * It you hit Cancel then the window disappears without saving anything. | |

31 | * TODO | |
d62c03cd | 32 | * - cancel/close should be consistent with properties |
