FX.76 Documents opens as a centered dialog, not a box in the corner

Owner 2026-11-06: Documents seemed to do nothing, and on large screens the placement was wrong. It opened as a small box pinned to the top right of the drawing area, far from the button. It is now a modal dialog centered on the window with the page dimmed, in BimCraft, PartCraft and CadCraft through lib/vault. Esc, the X or a press on the dimmed page closes it. Opening a file or a copy closes it so the file can be seen. Tested at 1280 to 3840 wide in the standard, Vector and Duncan layouts on SwiftShader; not on a real large monitor or in a Studio build.
