An app launched with `background: true` gets a real window from the moment it starts, just hidden. Nothing ever took it down: when the app that launched it closed, the child kept running with no way to reach it and no reason to be there. On the dashboard the only sign was a running dot on a tile the user had never lit up, and clicking that tile did nothing at all. Three things were wrong, and all three had to go: A window nobody has seen now dies with its launcher. UIWindow's close path closes hidden children the closing app launched, keyed on a marker stamped at creation. makeWindowVisible drops that marker the first time the window becomes visible — showing itself with `puter.ui.showWindow()`, or the user showing it — because from then on the window is the user's, and keeps running. The dashboard tile is a real handle again. focusExistingAppWindow only routed MINIMIZED windows through showWindow(); a hidden one fell through to focusWindow(), which leaves it invisible while handing it the keyboard. With no taskbar in dashboard mode the tile is the only handle on a background app, so that click had nowhere else to go. It now asks whether the window is on screen at all. The Files tab's row-click had the same one-line defect. And a background instance can't take a tile from the user's own session: an on-screen window wins, then a window the user has seen, then a hidden one. Removing the child then hit a crash of its own: ExecService's `remove` handler dereferenced the launcher's iframe to say goodbye, and the launcher was already gone. Throwing there aborts jQuery's remove() itself, so the window stayed in the DOM — running dot and all. That one also hit anyone closing a background app from the taskbar after its launcher had closed. The predicates behind all of this live in one helper, window_visibility.js, with showWindow() reading the same `hidden, not minimized` rule it spelled out inline before.
