I already downloaded TM903, but I didn't try it yet. I just look at the screen shots and it's great.
My experience with computers is not enough to develop a database like yours. I worked a little with mysql but i'm not a expert with it (not yet but just wait a couple of months).
Any help regarding the database will be wellcome (including the source code).
Should I change my mind and point to foxpro, Geoff?
As I told you, I'm not an expert in computers.
