problem with zoom in v2.x

I think i found some bug in version 2.x of APIs. I take the example
from this page - http://code.google.com/intl/ru-RU/apis/maps/documentation/examples/event-closure.html

then changed the version of maps from 2 to 2.x and added
GLargeMapControl to the map, this is what i have - http://alienweb.ru/example.html

When InfoWindowHtml is opened and you try to use zoom function, there
is an error with google maps scripts.
