I put the debug and save file into a zip for each of these

Crash #1: http://filebin.ca/yvkpve/Crash1.zip or http://filebin.ca/yvkpve

Crash #2: http://filebin.ca/ekkens/Crash2.zip or http://filebin.ca/ekkens

Crash #3: http://filebin.ca/rmdhqg/Crash3.zip or http://filebin.ca/rmdhqg

For crash #2 and #3, they occurred around the same time (game wise). I had played off of the previous autosave. The following time I think I recall a city, the tech window, and the spell window all prompting me for attention.

Additionally, after crash #3, I got a dialog box from Windows behind the "stopped responding" dialog box which said "R6025 - Pure virtual function call"

Lockup #1: http://filebin.ca/cnnnxb/Lockup1.zip or http://filebin.ca/cnnnxb

This lockup occurred in a combat initiated by a group of wandering monsters. I had just finished a combat with a solo hero, and moved him back into a newly conquered city.

During the combat which the wandering monsters initiated (with my sovereign, a sand golem, and two units), my sovereign had the name and picture of the hero I had just been using, but all the spells, equipment, and stats  as she usually does (according to her card). After about 3 turns, the "end turn" button grayed out and I couldn't advance. It held for a good minute or two, then when I alt-tabbed to close the program it crashed.
