Data wont stay saved in Database using Pysqlite

[azrael]

I am working on an application using Python, wxPython and Sqlite
(Pysqlite)

So my problem is that I can connect top the database. When I open a
dialog through a form I am able to make a select, even insert data
into the database. Even if I open again the Dialog.

But as soon as I close the main frame, the new inserted data is gone.
I don't get it I tried everything. Has anyone any idea. Please any
idea. It's kind of urgent
