I would recommend that you try installing Remote Utilities monitor driver and see if the issue persists. In version 6.9.x.x the driver installation is disabled by default (the corresponding checkbox in the installation wizard is unchecked). But you can install the driver after the Host has been installed - just open the Host settings, navigate to "Driver" and click install near the "Monitor driver" option:
Could you please send us the Host log to firstname.lastname@example.org. You can locate the Host logs in the C:\Program Files(x86)\Remote Utilities - Host\Logs\ folder. The log should contain information about connectivity problems if any.
We are currently investigating our options when it comes to resolving the closed lid issue. Unfortunately, this issue may potentially be caused by factors we do not control (such as how the display is shown in that state) and that may even vary from hardware to hardware. We will do our best to resolve the issue though.
