There is a weird bug in QDateTime Component.when I put a Date/Time Edit component on a dialog and enabled the CalenderPopUp property, then i ran the program and if the dialog will exec(), When i clicked on the the month button the system stops working and exit application forms happens. I've submitted it in bug report with a sample: (Please vote it )
