Teamviewer has been work on my machines for a long time. It was working thid AM. I installed Citrix Reciever and it now crashes when I connect to a remote with buttons ignore reopen and report. No matter which opsion I chose it reopens and I still do not connect. On the remote system, I have multiple open sessions from the bad MAC. I have unistalled the citrix reciever, and uninstalled and reinstalled teamviewer. Still have the same problem. I also uninstalled with "Appcleaner and Unistall" No Luck.
