Your Environment

• Version used:
• Operating System and version (e.g. Windows 10 1709 x64):
  OS: Microsoft Windows NT 6.3.9600.0
  mRemoteNG Version: 1.77.0.41252
  Edition: MSI
  Cmd line args:

Start with mRemoteNG.UI.Window.ConnectionWindow.Prot_Event_Closed in ConnectionWindow.cs at line 802, then trace the close flow into ProtocolBase.CloseBG at line 152. Reproduce the issue by closing the General panel after creating a new panel on Windows. Done means this action no longer raises the discarded ConnectionWindow exception.
