Should it? What makes you think so? Did the documentation advise you 
that that should happen? Does the program ask for 4.28? Does the 
program not work?

When a module is updated in !System, then precisely nothing happens, 
unless an application wants that later version and asks for it.

In this particular case, it would probably be utterly wrong to replace 
your 4.22 ROM version by a softloaded 4.28, but that subtlety should 
not be your concern.

Why would you want to Kill or Unplug FPE 4.22?
