QMessageBox closes entire application

[Boron]

1st. Use [code] tags when posting code here .
2nd. Perhaps it helps when you don't create the message box on the heap using new, but create it directly on the stack. The message box is only used inside the slot ErrAlert(), so there is no need to create it with new.
