Fast switching and encrypted records

Would it be possible to update Tap Forms to prompt for your encryption key when using fast switching in iOS4, or at least have an option for that? Even when you have a record that’s encrypted when you close Tap Forms and fast switch back to it your last record is left open. In the mean time, I’ve implemented the pin code: but I’d like to turn that off to save some time and rely solely on encryption — all of my records I care about protecting are encrypted. Thanks!
