This is a known issue with version 1.4 of AFE. The problem occurs with AFE
when the Macintosh Display Card 8*24 GC graphic acceleration is turned on and
may cause the system to hang, especially when formatting or erasing disks.
The problem does not exist with version 7.0 of AFE. However, AFE 7.0 has only
been tested with System 7 and the 7.0.1 version of the 8*24 GC software. The
current solution for System 6 users is to turn off graphics acceleration when
using disks with AFE 1.4.
