Hello Roger,
I'm glad to hear we were able to help!
Is there a way locking the viewer to Full control and view to force and user to use only Full Control and View mode?
Of course, you can enable/disable specific
connection modes for any user who connects to a specific Host. In order to do so please do the following:
1. Right-click on the Host icon in the system tray and select
Settings for Host2. Navigate to
Modes tab.
3. Select respective checkboxes for the modes you want to allow, e.g. in case if you want to allow the Full Control and View mode only, then select both the
Full Control and View only checkboxes and leave the rest of them unchecked:

Please note, that this is a global setting and will affect any user connecting to this Host. However, it's possible to further fine-tune access permissions for specific users using the respective
authorization method permissions dialog when setting up users for Windows security or RU security authorization methods.
Please let us know if you have more questions.
