Date Picker

I've got two boxes, both running Windows 7 and the latest Chrome browser. On one, I get the normal platform datepicker control but on the other I get this:

After a bit of googling, it appears this is possibly the native datepicker in Chrome. I can't figure out why one box would display this and the other not. Also, should the platform not handle this and prevent use of this other control (at least by default)?


I agree with what you are saying, but I see 2 the same boxes, so I fail to see the difference.
can you provide a simple example?
