I've been a windowblinds user for a very long time now, and I've never seen this feature work. Has anyone else? Is there some special trick to it?
While I will test this today at some point, with your active OD sub, you do have access to DeskScapes - a product more attune, and with more options for desktop art - than WB. Is there a reason you are not using it?
