[PyQt] QODBC driver not loaded (PyQt 4.3b1)

[叮叮当当]

Hello friends!

i use ms-access db in my pyqt app. it's work fine several days ago,
with pyqt4.2(PyQt-gpl-4.2-Py2.5-Qt4.2.3.exe).

After i had updated my pyqt to 4.3b1 (current newest version), my app
got an error-message when it run:

QSqlDatabase: QODBC driver not loaded
QSqlDatabase: available drivers: QSQLITE
QSqlQuery::exec: database not open

I think it was the odbc-plugin not been found by PyQt, but i don't
know how to tell it. (g:\qt\4.3.1\plugins\sqldrivers\qsqlodbc4.dll)

Could someone help me?
Thanks!!
