I have had this happen on a few occasions. I am into the game around mid 1941 during the lend lease turn. It does not respond and I have to ctrl alt delete to get out. I tried playing again and got the same result. I am running Windows 7/32bit. toshiba satellite 650. any ideas?

I had experienced the same problem with my legate and figured out that when upgrading him, don't get the individual stars which give strength in square, wedge and so on and especially the very first one on the list. Once finished you can upgrade all you like. I have made it to 220.
