No, there isn't a "nudge" feature on the latest version of Passageways instant messenger. The application allows you only to format your message using the Message formatting toolbar or to send documents, screenshots and start conferences:
By default, the new messages should pop-up on your screen and produce a specific sound. If it doesn't pop-up or produce that sound, I recommend you uninstall the program from your PC and then install it again. If the problems persist, use 765 535 1880
