In disk druid, pre-existing ext3 partition (from beta 1 install) comes up with the format option set to "No". Edit the partition, and the edit window comes up with the "Format partition" option selected instead of the "Leave unchanged" option, even though the partition was previously selected for no formating.
Still occurs with update-disk-07182001.img
This defect considered MUST-FIX for Fairfax.
Fixed.
