Well what do you know, Jimz18 might have fixed it for me.
So far so good, any "connection closed" screen works when I hit F5 to refresh, not ideal if I am piping script into the remote prompt via an automation tool but at least it works for manual typed connections again... so far at least!
Too bad LogMeIn isn't a mainframe system, then F5 would actually be a fix rather than a workaround. BTW, F5 gets me connected to the CLI as well. Good catch Jimz18!!!
UPDATE: Can anyone at LMI give us an update for when this issue will be resolved? We're quickly approaching the end of month 3 since it was reported and it is still happening as of a minute ago.
It might be because its opening POWERSHELL instead of a COMMAND PROMPT. Have your devs look at that. Seems someone changed something in the client or exe being called and now it's a different executable being brought to bear.
