The v1.7.19 fix (launching explorer.exe directly instead of xdg-open) wasn't sufficient on its own: Windows' foreground lock blocks SetForegroundWindow from a background WSL-interop-launched process, and Explorer just flashes the taskbar entry instead of raising an already-open window for the same folder.
PANDA_GUI.py's "Open Results Folder" button now routes through a small PowerShell helper that finds/opens the window via the Shell.Application COM object and explicitly forces it to the front via user32.dll's ShowWindow/SetForegroundWindow — confirmed working live.
Also: run.mac's dummy 28nm-node test geometry (.04/.04/.3 um sensitive, 3 um dead layer) had criticalCharge corrected from an unrealistic 150 fC (far above anything this device ever deposits) down to 1 fC, rerun at 1M events with Results/Current refreshed to match.
