I am learning how to create a switchboard from the Access 2003 Bible. The Command Button section indicated that I have a choice of activating On Click, On Dbl Click, or activating both options simultaneously as they are mutually compatible. The training does not provide a rationale for choosing either option or both options. Is the choice of design made entirely by personal preference, or is there some advantage gained by choosing one function over the other, or using both simultaneously?
