I have found one of the dreaded messages that occurs suddenly while working with Generations EasyTree. I had copied it recently during a "crash" while trying to use the search button (which no longer works, due to assured crash.)
This is the message that I had saved to my file:"
"THIS PROGRAM HAS PERFORMED AN ILLEGAL OPERATION AND WILL BE SHUT DOWN. IF THE PROBLEM PERSISTS, CONTACT THE PROGRAM VENDOR."
