Just as a general comment, asking multiple unrelated questions in a single post is a good way to get poor responses on all of them, as you’re basically asking for several separate conversations to become interwoven with each other. And when there’s a problem, include whatever code is required for people to be able to reproduce the issue (but only the required code; the effort of paring things down to the bare minimum that causes the issue often leads you to discover the solution for yourself).
