Something I can't explain. Whatever the a/c the SHIFT+8 key combination opens the Weapon Control Panel. It works fine for every a/c where Weapon is installed except just one  the A2A P47 + AccuSim (all others A2A models + AccuSim are OK).

The window titles list seems to be correct :
[Window Titles]
Window00=Main Panel
Window01=Pilot's Notes
Window02=Mini Controls
Window03=Payload and Fuel Manager
Window04=Map
Window05=Radios
Window06=Maintenance Hangar
Window07=Weapon Control Panel
Window08=HUD
Window09=HUD Glass
Window10=none1
window11=none2
Window12=none3

an each of the [WindowXX] matches the corresponding title XX including the one that makes trouble :
[Window07]
Background_color=0,0,0
no_luminous=1
size_mm=1024, 170
position=7
visible=0
window_size=1.000, 0.170
ident=10901
zorder=2
gauge00=CSWeapon_panel!CSWeapon_panel, 0, 0, 1024, 170

The WCP is present in the FSX views menu/instrument panel list at the position 8th and I can of course open it from there but I can't with SHF+8, the key combi that is mapped to my joystick.

Any idea ?
