Thanks for quick response JMM.
Yes 2F (i.e. the corrected version) over version 2e. Waterloo pack afterwards.
Peninsula pack in separate HW install.
UPDATEMade fresh install; added key; patched with incl patch to 2e; patched to 2F. No mods. No campaign packs.
F keys still dont function correctly, different keys work in different scenarios.
Sound is a bit strange sometimes audible sometimes not. Quiet in most cases.
PWGM (still in it's old separate installation) - v201e - loaded La Corogne - all units immediately flee.
So I think cause is not the F patch.
Think the PC is OK as :-
Theatre of War #1 - openGL - works perfectly
Theatre of War #2 - directX works perfectly
Achtung Panzer: Kharkov 1943 - DirectX 9.0c works perfectly
Heaven DX 10/11 benchmark works perfectly
DXDiag reports no issues.
Only real change in PC is my VGA card from 9800GT to GTX460 & driver update.
Perhaps this VGA card is an anti-Napoleon Royalist?
