1. If you need to programmatically make a field usable at run-time,
then you should be using the FldSetUsable() call.
2. FldSetAttributes should only be used as a last resort, when the
API to do what you want isn't available.
3. If you do call FldSetAttributes, then you _must_ call
FldGetAttributes first, change the flags, then immediately call
FldSetAttributes _without_ calling any other field object routines in
the middle. Calls to FldXXXX routines can change the value of the
field attributes, which would make the copy that you loaded with the
FldGetAttributes call invalid.

The Simulator uses a debug color palette to make it more obvious when
your app has drawing errors.
