Help with True Launch Bar on Windows 7 Taskbar

Well, it's been a bit frustrating. I changed so many things, so many times, that I'm not sure what did it, but I do have two rows of icons in a single-row taskbar. It seems like it happened after a restart, so maybe I should have been logging off or rebooting after each change. I think it was the button metrics, and I was able to keep the Windows 7 skin.

In the process I moved a menu with my drives on it into a new folder. I had C:, D:, and N: drives stacked up vertically, and when I moved them they rearranged to side by side, and I don't know what to do to reverse the change. The vertical layout became horizontal, and I can't get it back. I have moved the menu back to the main bar, but the change stuck. It's frustrating because the sub-menus of C: cover up D:

What should I do to have a vertical layout on a menu?

Thanks,
Ben
