Quaterstaves and pixie wizards

[Diceman]

Starting a new 4E campaign. One player is playing a Hybrid Wizard/Cleric Pixie.
Having issues getting the program to allow the character to equip a quarterstaff.
The "official" size of Pixies is tiny. When I try to purchase a quarterstaff for the character it is not a valid choice.It states that small creatures are not allowed to equip two handed weapons that are not "small"

So two problems:
a) Program is Calling Pixies "small" instead of "Tiny"
b) Unable to create a custom quarterstaff that the program recognizes as either "Small" or "tiny".
I used the editor to create a custom quaterstaff using the"new/copy" and then gave it the weapon property "Small". So then it allows me to purchase the custom weapon as a valid item but still recognizes the weapon as a medium weapon.
I really don't want to have to use the WOTC program.
Can someone help me address this issue?
