I haven’t created one. I also went looking for a trixy one that might have infiltrated over the weekend. I can say there were no hostile borders.
You point of the version sounds like an excellent place to look. I had thought I only had 1.10. I thought I had deleted everything and reinstalled it all. If there is a 1.7 out there, it arrived in stealth. I think I start a global search for clo*.jar files. Thanks for the help!
