Now() does not update in Ajax/full browser version
In IE plugin, Now() polls the operating system every second. You can easily see that it works by creating a text object and setting the value to be =now().
This is useful for many reaons, for example when wanting to switch tabs at set intervals or carry out other actions automatically at set times.
However, now() does not refresh in Ajax view unless a user interacts with the application (e.g clicks within the app window). Therefore, timed events cannot run in Ajax.
