We have been having intermittent Internet connectivity issues in which d7II claims it doesn't have an Internet connetion and/or it cannot authenticate with our FTP server. This has happened on multiple computers but appears to be intermittent. Another thing I have noticed is that if I go to Main > Config > Servers/Email > FTP Servers and click "Test Login" I get a small pop-up window that simply won't go away. I have to manually kill the d7II task in order to get it to go away. I just tried on the same by running the d7ii_old.exe in my d7II directory and it doesn't not behave the same way.
This is causing us issues because d7II relies heavily on an Internet connection and our FTP server. Please look into this. I have attached a screenshot of the pop-up.
