LCL's CheckMouseButtonDownUp (controls.pp) applies a hardcoded 3px position check on top of Windows' own WM_LBUTTONDBLCLK detection. Touch/pen taps routinely land 4-10px apart, causing the double-click to be silently downgraded to a single click before DC sees it; Total Commander (native Win32) handles WM_LBUTTONDBLCLK directly without this extra filter, so it works correctly. Two fixes, both Windows-only (LCLWIN32 guards, zero effect on Linux): 1. Raise Mouse.DragThreshold from 5px to 10px at startup. Touch/pen wobble during a tap easily exceeds 5px, accidentally starting a drag and swallowing the click. 10 logical pixels is sub-millimetre for a mouse and imperceptible in practice. 2. In MainControlMouseDown, track the last left-button-down time and position. On a second tap that arrives within GetDoubleClickTime and within 10 logical pixels but without ssDouble in Shift (i.e. LCL rejected it), call DoMainControlFileWork directly. The guard gMouseSingleClickStart = 0 prevents double execution in single-click mode, where MouseUp already handles the open. |
