[development] Saving admin settings

Lately, it seems that I'm stumped by what turns out to be 'weak eyes.' Here's another. I have a callback to the function in a module that provides the admin settings form for the module. The form appears just fine, and functions correctly. At the end of my form definition I have the obligatory return system_settings_form($form); The issue is that none of the form data is stored. The form is generic...no submit handler specified. Jeff
