There is a possible bug when trying to use *QAxContainer.QAxWidget*, * QtGui.QGraphicsOpacityEffect* and *QtCore.QPropertyAnimation* in the same application.
This happens when trying to animate a widget's opacity (creating a "fade out" effect). The animation won't update correctly if a QAxWidget is present somewhere in the same window. The bug can be seen here: http://itayb.hostzi.com/eventloop_doesnt_update.avi A test case that causes the weird behavior is attached. Thanks!
