[news.eclipse.platform.swt] How to dermine if Shift Key is down?

["Sergey V. Gomanyuk" <sergg@xxxxxxxxx>]

I tried following:

displayKeysListener = new Listener() {
    public void handleEvent(Event event) {
        if(event.keyCode == SWT.SHIFT) {
            if(event.type == SWT.KeyDown) {
                Utilities.setShiftKeyDown(true);
            } else if(event.type == SWT.KeyUp) {
                Utilities.setShiftKeyDown(false);
            }
        }
    }
};
Display d = getWorkbench().getDisplay();
d.addFilter(SWT.KeyDown, displayKeysListener);
d.addFilter(SWT.KeyUp, displayKeysListener);


It works until popup menu in Eclipse view invoked, display doesn't send any 
key events while menu is active. Why? How to find out if Shift key had been 
pressed just before action from popup menu was invoked?
