    Known Problems

    Version 3.31 of this driver is named differently than version 3.30 which shipped on the NEXTSTEP3.3 CD-ROM. Installing the newer version will leave both drivers co-resident, so both versions will be visible in Configure.app. Remove any instances of the older version and replace them with instances of the newer driver.
