Daniel do you see this configuration page

use the scroll bar at the bottom to scroll over to where you should see Leo - same with this new interface here

there is a kind of hidden scroll bar here on this page at the bottom under the previews
also if you are seeing this page here to get your info as you presented here in this forum earlier I can not see other than you are just not looking completely at the interface correctly to use it. as seen here - do you also see this screen correctly...

or this screen when in the new interface with the about windowblinds tab is pressed...

Also download and look here at this small video of how to use the config page for new interface...
LINK This opens with win media player...
good luck and let us know?
