QSystemTrayIcon does not show message

I'm trying to use QSystemTrayIcon to display a message after application initialization. My main loop immediately calls Init() function by using a single-shot timer with zero period:

int r;
QTimer::singleShot(0, &app, SLOT(Init()));
r = app.exec();
return r;

After some initialization steps, and the creation of trayIcon in MyApplication::SetupTrayIcon(), where the proper icon appears without problem, I call another function in the MyApplication class where I do.

QApplication::processEvents();
_pTrayIcon->showMessage("TITLE", "TRAY TEXT SAMPLE");

I tried making the QSystemTrayIcon instance a child of QApplication (MyApplication which is a subclass), a QWidget child, and nothing happens. Even without any parent, nothing happens.

System is Windows XP SP3, nothing out of this world.

Solved.

Explorer.exe has system tray balloon tips disabled through system registry (HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\EnableBalloonTips was set to 0).
