Shoutbox

I can't help myself, but I am not able to make it run.
If I set the event up - fill the program/link window and description and press Add, it only shows this popup:


Finally, another popup saying something like "you have missed following event" remains open.



However, in the task scheduler window, there is written "A program or a web page can even be executed with the pop-ups."

So maybe it can't be executed automatically at all at this moment...
