Thank you for your message.
Am I right in assuming that you use Viewer for Mac/Linux of the latest 1.0.6.q Beta 6 version and Host for Windows of the latest 184.108.40.206 Beta 4 version? If this is the case, then could you please check if you have the Disable clipboard transfer
in the Host Settings -> Other tab
In addition, please note that this is a Beta version of Viewer, so it has limited functionality and more features will be added at later stages. You can find the full list of currently available features on the first page of this thread in the first message
As for the issues with the arrow keys, unfortunately, we couldn't reproduce it yet, but we will additionally test it out to see if it can be fixed in our future updates.
Please let us know if you have other questions.
