Thanks Eric. I agree it is stupid. I love HD Architectural but after a month of heavy usage, I'm seeing a number of annoyances that continue to irritate me.
I'm sure I have a lot to learn, but I'm pretty sure I'm doing most things correctly. I see the Pro version solve a lot of issues, but at $300 more, it isn't worth it.
You suggested changing the thickness of the floor structure. In Architectural, you can not change the joist size, as far as I can tell. Is that what you were referring to?
