Code Completion -- First Item isn't selected automatically

In 3.0 version of Resharper, Code Completition feature automatically selected first item in drop-down list, but in version 4.0 you need first to press Down Arrow to select first item -- it's very inconvenient, especially when only one item is left in the list and you are expecting that pressing Tab key put this property or method name in code. Is there some option that controls this behaviour? Why do you change this from version 3.0 to 4.0.
