I'm using Chrome and notice that at backend, when a drop-down field triggers visibility of other fields I need to make a selection, click somewhere else on the page (make that field out of focus), then click on the drop-down field again to make the hidden fields appear. Otherwise they will stay hidden.

No such problem when using Firefox, the hidden fields appear immediately when I make selection.

It's not major problem but when I first using CB, I missed quite a number of settings because of this. Only later I accidentally find the weird behavior.
