Calendar is not clickable

hi, I’m working on setting dhtmlxCalendar with a textbox in chrome browser.
when I click a calendar icon, the mini calendar UI shows up.
but then, the calendar is not clickable at all and doesn’t event close once it opens.
(no response back once the calendar opens.)
when I click specific date in a calendar UI, the click event is not working in the calendar and no date is selected.
Also, click event works well in internet explorer, but not works in chrome.
I want to know why it happens only in chrome browser and how it can be fixed.

My chrome browser is up-to-date version, and OS version is windows 7 enterprise service 64 bit.
Thanks in advance.
