Activate Application Switcher strange behavior

When I use the CMD Tab macro, the application switcher appears but when I release the buttons, it disappears. Also, when I mouse click on an application in the switcher, I do not get a menu of options.

Am I doing something wrong?

See if the following post resolves your issue:

The switcher should stay visible as long as you hold the command key down.

When the switcher is visible, you can click and hold on an application icon to get a popup menu of options.
