The curtain keeps opening when I reach for the menu bar — how do I stop that?
Short answer: Raise the Open delay in Settings → Advanced → Junk Yard Edge Curtain, or dock the curtain to the right in Settings → Junk Yard so the top edge stays free for menus.
Give it a longer Open delay, or move it off the top edge. In Settings → Advanced → Junk Yard Edge Curtain, raise Open delay so the curtain only appears when you pause at the edge. Or set Dock to: Right in Settings → Junk Yard so the top edge stays clear for menus.
If you never use it, switch the curtain off altogether — the board is still one shortcut away.
