I have a problem: I tested a "message box" type configuration, programming it to be run at each login on a specific machine. It works perfectly. My problem is that I deleted the configuration that created this message box and now that I create a new configuration that is supposed to undo all message box, it fails saying that there is no pop-up window programmed (but in fact, the window clearly appears at each login...). Is this normal or is it a bug? I do not know how to undo this now so any help would be appreciated.
