Patch 3 is now available.
Version 2.17 Patch 3
======================
Fixed a bug that could cause numerous abnormalities when minimizing the game or quitting the game and changing your video settings.
The game can now run without a sound device installed. It will generate a message if it does not find a sound device.
Fixed a couple bugs in the offline missions that caused A.I. flights to disappear or not take off. NOTE: There is a potential backwards compatibility issue with older missions using the I-16, P-47M, P-47D-25 and the F6F that may cause different plane types to show up in there place. If you have this issue you can fix it by editing the mission and reselecting the correct plane type.
Changed how screenshot files are written out to a file. The new method does this at a controlled pace and therefore results in a delay before the next screenshot can be taken. The length of this delay is dependent on your video settings.
Increased hardness of the city blocks in the industrial city center.
Reprogrammed the combat trim on the I-16 to remove a roll tendency.
