Just dug into these, would have been very nice to read the first post that says how to address these. And after playing with it for a bit, I thought DUH. Then I just wrote my own sub to pull the currently visible list from the tab control. I named it, TM_GetVisibleListFromControl. If you're interested in more people using this, that would probly be a helpfull sub to add.
Unless I'm missing it, and you have it hiding somewhere I don't know about. There's only one reference to how the actual lists are addressed, even tho, if you think about it, it should be pretty obvious. But it threw me for a good 10 minutes until I really paid attention to what I was doing cause I was annoyed with it.
