My magna-doodle lasted for about a year before the glue started disintegrating. As to storing detail, its no problem. Just stick a small slate to the back of it and Voila! You have the means to store more stuff. You could even rig up a pencil with a small magnet on the other end so you can use the same 'pencil' for both sides. But that, of course, comes round again to which pencil to use - and which ones stay whole for more than a dive or two. - Helen ooo----------------------------------------------------------ooo Helen Johnstone Blyth Software Ltd Phone +44-(0)1728 603 011 +44-(0)1728 603 019 x52 Fax +44-(0)1728 604 154 email: Helen_Johnstone@mh*.bl*.co* ooo----------------------------------------------------------ooo
