DarkStar, Thanks for the reply. But check again. In Alpha5 they sorta do, but not exactly. Try this: minimize all tracks and lanes. Now take one lane, and enlarge it a substantial amount. Then Ctrl. Scroll the tracks. The lane will enlarge in proportion, but it will never get smaller than the size you originally enlarged it to. The lanes should follow the exact behavior of the tracks, and be able to fully minimize with Ctrl Scroll. thanks...BB
