Hmmm, this doesn't happen in my case, and I don't even accept() the QEvent, 
but I don't think it has to do with it...

The only _real_ difference to your code is that I use a separate class 
(instantiated with a NULL parent) for the key event filter. The event filter 
is not integrated with any widget class my application uses - it's just 
derived from QObject.

...
...
class KeyPressFilter : public QObject
{
  Q_OBJECT

  public:
    KeyPressFilter(QObject *parent = NULL) : QObject(parent) { ; }

  protected:
    bool eventFilter(QObject *, QEvent *);
};
...
...

...
...
int main(int argc, char *argv[])
{
...
  QApplication myApp(argc, argv);
...
...
  // setup key event filter
  keyPressFilter = new KeyPressFilter();
  myApp.installEventFilter(keyPressFilter);
...
...
}

Does this help in any way?

People who are funny and smart and return phone calls get much better
press than people who are just funny and smart.
