My son played this at school and was so completely entranced he pestered the teachers for details and then asked his Mum and Dad very nicley with all the details! He's not usually so fascinated by something and had gone about asking it so well I was keen to support him particularly as it is not just a minless game - it is designed to teach programing the programming language Logo but the cost of the regular product is quite high for home use. I found this earlier version and ordered it as a surprise present for him and was relieved when it worked under Vista. Needless to say he was very grateful and enjoyed it for some time.
