Hi, I watched your video, and the conclusion I have reached to, for this to work both in Windows and Mac, is to develop the application in Adobe AIR using Flash. That works best for me! Everything is crystal clear, except for the mySQL part. What do you mean by saving it as a mysql file? Does it need any special formatting, or just a file with the extension ".mysql" or ".sql"?
The reason for my bid being higher than the budget, is that this is a project of a relatively large scope, so I had to bid with a price that justifies the work and effort. If you have any questions, let me know in the chat. Looking forward!
