Entire div is not working in Chrome

I have a page divided between two divs Ba and Bb, everything in Ba works, everything in Bb does not. I'm in the process of dividing and conquering this problem. Does anyone know why Chrome would effect开发者_如何学Goively disable a logical division of my page and IE would not?

By not working I mean you can't click in the text boxes, nothing happens when you hover, you can't click on the buttons, etc.

This was a z-indexing issue. There was an invisible div that had a z-index higher then everything beneath it. Hence all the issue were only one issue. For some reason Chrome, Opera, IE9 and likely more standards compliant browsers picked this up while older browsers did not.
