Wouldn't this defeat the purpose of your login? e.g. I log in to your 
app, edit something, step away for 3 hours, bob comes in, clicks OK on 
the edited dialog and voila, still validated in the system.

Why not simply pop up a password box when the OK button is pressed if 
the user is no longer logged in?

As in:
User starts app and validates himself via a password
User edits a record (or whatever)
User stops typing for 3 minutes.
You let the timer expire.
User clicks OK.
User has no access, so pop up a password dialog appears to re-validate him.
