Thank you for your message.
Cursor options are set individually for each connection (an item/entry in your address book that represents a remote PC).
In Viewer, right-click on the connection in question and select Properties. Go to "Cursor" and then select the appropriate option.
Every other PC I see my main cursor then another one inside the remote PC. It super laggy and the cursor changes based off what your hovering over.
Perhaps you have the rendering of remote cursor option selected. Try setting it to "View only mode active" or "Never" if you only want to see the local cursor.
Hope that helps.
