Padding. Usually, structure fields are put at multiple of there size. If there is a multiple of 4 bytes that is not a multiple of 8 before your double, it is shifted. But it is architecture and compiler dependant. You can used #pragma pack with a performance loss or rearrange the fields in your structure. -Fred _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
