Post and Beam Issues

[alobartn]

I've two questions.

1. When specifying a railing, I'm using "Post to Beam." How can I change the thickness (height) of the beam? I've tried in framing defaults>Beam Initial Values, which apparently is the wrong place. I know this is basic, but I'm unclear on where to make the change.

2. In the drawing below, there's a post showing that shouldn't be there. "No Halfpost" is checked. I assume it has something to do with how the railing has joined the adjacent wall, but they appear connected. I know I can draw the posts, but I want to get this railing thing down. Thanks for any help.
