Panic Button is intended to help people that support end-users, either sysadmins/helpdesks, or those that simply help friends and family. I got the idea after getting frustrated by reports like I had this error message on my computer. It said that the whatsit had caused a thingy operation. No-one ever wrote down error messages, and could never remember what they said. I tried to teach people how to take screen shots, so that they could send screen shots of error messages, but that didnt work.
