This bug has been reported by the GB hotline. This is common with installed Sound Blaster Audigy chipsets. The game will lock up and freeze during the sound calibration sequence. This bug is visible with the camera behind the player's car and when there is some distance between the two cars. Changes: Sometimes on the track (any motor circuit), when the heat haze is actived, then the car who precedes (or who follows) the player's car disappears. This patch will update Grand Prix 4 to version 4.0. After installation of patch, game will then be GP4 v1.02.
