Displayed track libraries

[Jeff]

If I use the checkboxes in Options to change scales, and there are other scales already displayed, I want the displayed scale(s) to go away and let me just have the current scale displayed.

i.e.
1) N scale libraries displayed

2) Change the checkboxes to deselect N scale and choose HO/OO scale

3) Displayed N scale libraries go away and upon choosing the new scale, only the new scale's libraries are open for choice. No, not if BOTH scales remain checked, only if you really are, by your choices in the Options menu, changing scales. This allows things like mixed scales on the same layout [as in using N scale as HOn3].
