to answer a few of the questions from comments on the quiz:

Thanks to everyone for gratulations and thank you messages.
It's okay to use a web search to get the result.
I was suprised for several people knowing exact day. So maybe we raffle top prices within the participants with exact date and other prices with all with right year. We'll see.
Wether it's Real Studio or REALbasic? That name change didn't change the product.
We are looking for version 1.0 of the collection, not some individual plugin we had before.
Also the quiz is not about the founding date of our company.
