I've noticed that when using TWX scripts which send messages via sub-space, that they don't appear in the comm window in Swath when the sub-space radio tab is selected. If i scroll back in the main window I see the messages. Do I need to set the sub-space radio channel I am using in Swath somewhere and if so where?

I think the Swath comm window only shows incoming messages, not outgoing ones you send either manually or via script.

Actually just the opposite. For subspace it only shows outgoing. I had someone send me a subspace message from the command prompt and it only showed in the main window.
