From: PURVIANCE on
Every now and then, some or all of the database objects that i have assigned
to "custom groups" get unassigned and appear in the "unassigned objects"
group. I've even had database objects get mixed up and appear in the wrong
"custom groups"

When this error happens I have to reassign all of the database objects to
their old "custom groups" and this is very time consuming.

Does anyone know what causes this problem?
