On the web almost all interaction is based on the single-click concept. You click once to follow a link, you click once to press a button, once to open a dropdown select list, select a radio button or checkbox element etc.
So if you were to double click an element that toggles (e.g. like a checkbox) you would expect the first click to change it from state A to state B... and the second to change it from state B back to state A. (e.g. unchecked - checked - unchecked)
This works as expected in all browsers except IE. In IE double-clicking a checkbox will only switch the state once from A to B.

Realistically this isn't a major issue as most users are unlikely to double click a checkbox... however based on the number of post on web forums and newsgroups about how to stop users from double clicking and re-submitting data - it certainly does happen.
Known Workarounds: None.
