mage weapon feats

[HighLordDave]

I just started a new game and am having some problems with a wizard's attack bonuses.

She is an elf Wizard 3/Ranger 1, is not wearing any armour and is dual-weilding the Wispering Staff and Craftsman's Hammer. When I go to the character record screen and look at her attack modifiers, it reads:

Main Hand: +1
Base: +3
Weapon: +1
Proficiency: -4
Abilities: +1

Off Hand: +1
Base: +1
Weapon: +1
Proficiency: -4
Abilities: +1

If she only has one weapon, the proficieny penalty goes away. My question is this: a ranger wearing light or no armour attacks as if they had the two-weapon fighting and ambidexterity feats, so why is she being assessed the dual-weilding penalty?

Thanks in advance.

EDIT:

Nevermind; I just broke out my D&D3 rule book and looked it up; the two-weapon fighting rules have been applied under the proficiency category and the off-hand weapon is a medium weapon, so the penalty is -4 for each hand. I guess it pays to RTFM, huh?
