I've been bitten by the DRC window before, but KiBot[0] renders that moot. I have it running as a pre-commit hook, and it generates my Gerbers and everything. That way, all this stuff is automated and I can't make a mistake.

Check out my project's config:

I wholeheartedly recommend KiCAD, it's fantastic.
