I've actually fiugred out what's up with that problem it has to do with the weird way Game Maker 7 handles reading and writing decimal numbers to a file. It reads the number always using a period for the decimal point, but when it writes the number, it depends on your computer. So if your computer uses a comma for the decimal point, then Game Maker doesn't know how to read the number back again.I think I know a way to work around this, so if I ever get another update out, hopefully this particular problem will be fixed.
