BackTrack 3 airoplay-ng crash

[quinbd]

Hi, i am trying to learn to crack WEPS, but when i use aireplay-ng the entire computer freezes. I am using BT3 Beta USB version, live, on 2 GB ram, and Intel pro wireless 3945ABG.
I am using the standard drivers for the Intel pro wireless 3945ABG. I have tried to use two commands one for association with the AP, and the other for packet interjection. I press enter and the computer freezes instantly and the terminal displays a few line of the process. The lines it does outout are the same as if it was working, and no errors are given. Then the computer freezes completely. I am using the newest version of BT 3 USB version.

This is the bug and fix section. Note the "FIX" part. Moving to the proper location.

Use ipwraw for time being, atm only ipwraw supports full injection and iwlwifi only supports Mode managed/monitor.

Sorry about the wrong section, but can you tell me how to use those drivers, i have tried and can't seem to get them working.
