1. LM9 comes with 1 panel by default (lets refer to it as "P1")
2. Create a new panel (lets refer to it as "P2" (giving you a total of 2 panels).
2. Set the preference of P2 to top, then bottom.
3. Now select P1 and set its preference to top then bottom (it should move P2 above it)
4. Either select the Window List from P1 and move it to P2 or delete the Window List from P1 and add a Window List to P2.

Pictured above is my layout. P1 with "Quick launch" style shortcuts below and above it a Window List to switch applications.
Issue: During the course of the day, my Window List will disappear. I can still click it, but I can't see the Window List at all.
Note: I can make the Window List reappear by repeating steps 2 & 3 mentioned above or rebooting.
Is there something I can do to keep my layout or correct this behavior?
(By the way I have been running LM9 for a few months now and I love it, thank you devs.)
