It is an interesting interface issue though, and there can be cases where you have to only make one choice, if you're interested to do so, but if you accidentally do that there isn't a way to select nothing again. Some dialogs solve that by having a Clear button, though that seems wrong somehow.
In Adobe products they have a not bad solution to the issue. Next to some drop down menus are checkboxes. If you make a selection from the menu, the checkbox next to it gets checked. There are several of these within the same dialog, and so you can easily specify a lot of things at once, and if you have made an incorrect selection, you can uncheck the box next to that menu.
