This version - when restoring a window's position with "use multiple monitors" enabled, properly determines whether or not the window can be displayed on a physical monitor (tnx to Bill G4WJS) - corrects a regression in WinWarbler 8.5.7 that prevents buttons in the "Mixer adjustments" panel from working correctly (tnx to Tom K8WDX) WinWarbler 8.5.8 is available via the DXLab Launcher or via 73, Dave, AA6YQ
