Bill,
I played the 1806-07 Winter Campaign.
I loved the double battle map and pretty well spanked the Russians in both cities. I took Pultusk and the bridge objective.
I used the next stack button to move units which made for a very confusing atmosphere in a good way. Historically, the situation was very fluid and confusing so I wasn't always sure which submap I was moving troops on for the first dozen turns, which was fine. I started getting a feel of which Corps were on which map as the battle flowed and was able to get a feel for where the Russians were. I pushed where they weren't and I pinned where they were. The AI was a bit passive, but I didn't go looking for trouble by probing the entire map, either. So it played well.
When I used good tactics, I had success. When I didn't I got burnt. That's the way it should be.
I was able to play the 36 turns in three after work settings of about an hour or so each evening. Very enjoyable.
Did you make a "for the heck of it" version with clear weather? That would change the flow of the game, as would a clear weather day for Eylau. Nice sunny warm days with no snow, etc. hehehe... AL-ways tinkering.

Family and Post Office are fine. Hope you and yours are well.
