No zoom buttons, the balloon is shown incoorectrly

You may do the fix by yourself:
in lines 363, 372, 373, 374, 375 replace:

map.addControl(typeControl);
map.addControl(new YMaps.ToolBar());
map.addControl(new YMaps.Zoom());
map.addControl(new YMaps.MiniMap());
map.addControl(new YMaps.ScaleLine());

with:

map{$this->mapNum}.addControl(typeControl);
map{$this->mapNum}.addControl(new YMaps.ToolBar());
map{$this->mapNum}.addControl(new YMaps.Zoom());
map{$this->mapNum}.addControl(new YMaps.MiniMap());
map{$this->mapNum}.addControl(new YMaps.ScaleLine());
