Seems to work just fine Paul, no problems so far with all the different campaigns I have thrown at it - with the exception of Lonestar's DCG Solomons 1942-45 V1.5 (unmodded)- get planes exploding at the start (this is without the Ki-45 add-on files included as option with his campaign).
This could be the campaign, 4.11m, or DCG. I am unsure as to which.
