    Default Database connection problem

    Hi to all!

    I've upgraded to 4.4.1 and my app cannot start because of following error:
    Qt Code:
    1. warning: QSqlDatabase: QMYSQL driver not loaded
    2. warning: QSqlDatabase: available drivers: QSQLITE QMYSQL3 QMYSQL QODBC3 QODBC
    To copy to clipboard, switch view to plain text mode 

    I've compiled mysql plugin and copied it to all places where is needed (libmysql*.dll) but it still does not work. Any help please?
