Why do you have Bar2 enabled at all, if you use Alt to switch Bar1 to it?
But you're right, the "Default State - Hide" is currently bugged. If you want a bar to hide, use the "Always Hide" option in the General Configuration Menu.
And remember, you do not need the bar to be enabled or visible to be able to switch to it using alt, for example.
Thanks Nev. On your first few working version of B4, I couldn't get it to work properly without showing Bar2, and ever since, been doing that way. I'll go make the necessary adjustments. Is the "Default State - Hide" still bugged?
