In at least Snow Leopard, and possibly older versions, hot corners are nearly always hot. For example, if you setup a hot corner to show the desktop you can drag a file from a finder window to that hot corner and cause it to fire allowing you to place a file on the desktop or a folder on the desktop easily.
