Popup menu does not scroll properly on Symbian

Hello Folks,
I have a somewhat strange UI usability eeker - popup menus cannot be scrolled.

My app opens a popup menu like this:
void QtAllFeedTreeView::CmdSortClicked()
{
QMenu *menu = new QMenu(this);

menu->addAction(showAllAction);
menu->addAction(showBookmarkedAction);
menu->addAction(showUnreadAction);

#ifndef Q_OS_SYMBIAN
//no sense in that on Symbian
//menu->addSeparator();
#endif

menu->addAction(groupDateAction);
menu->addAction(groupNameAction);

#ifndef Q_OS_SYMBIAN
//no sense in that on Symbian
//menu->addSeparator();
#endif

menu->addAction(sortAscAction);
menu->addAction(sortDescAction);

menu->exec(QPoint(ui.CmdAdd->pos().x(),ui.CmdAdd->pos().y()));
}

The menu has more items than can be shown on screen. However, no scroll bar is shown -> makes scrolling unintuitive.

I will upload a video in a jiffy...

With best regards
Tam Hanna
