I would say you'll have to monitor an event that fires if you disenchant something or prospect something. I have no idea which are the proper events. But there are a least two ways to find it out:
1. Look at
http://wowprogramming.com/docs/events for the events.
2. Or create a test frame and try RegisterAllEvents (
http://wowprogramming.com/docs/widge...isterAllEvents). Then disenchant/prospect something and see which events are fireing.
