When I get to Mission 18-3 in Cannon Fodder, the game crashes each time I get to the room with the enemy jeep. Has anyone else encountered this problem or has a solution? I'm using Windows 7.

Thanks in advance!

OK, I had the same problem

The only solution I found was the cheat found on this forum

...Go to the map screen, hold Ctrl and type "fodder", then leave the map screen and press Enter. ..

There are actually two jeeps in this phase: one to the north of your drop point, the other more to the east.
Try to destroy the first jeep (to the north) as quickly as you can after starting the mission. If you make it in time, you should be fine after that.
