At Arc 10.0 I can configure the properties of an Arcmap numeric table field using its Field Properties > Numeric… > and then clicking the “Show thousands separators” checkbox on.
But I would like to make that setting permanent (i.e. always show thousands separators) for every numeric field, across every table, for every map document, forever.
This doesn’t appear in the Arcmap Options, nor in AdvancedArcMapSettings.exe.
