I have that problem too... except my BossPrefs is hidden too! I don't know how it happened but when i clicked on Poof! from inside BossPrefs, both poof and bossprefs were in the hidden category. Obviously, i clicked on them to make then visible again, and exited bossprefs. As usual my screen refreshed (or whatever you call it, happens after poof closes too), and bossprefs and poof were still missing!
For some reason whenever i click on poof and bossprefs to be in the visible section, when i go back to the visible section they are not there anymore! then i go back to the hidden section and there they are, and no matter how many times i click it to make it visible it always goes back to the hidden section.
i've tried removing it, restarting my iPhone, installing it again, and doing the same thing, but it just keeps hiding the icons.
How do you get to BossPrefs or Poof! if the icon is hidden? And how do I fix my problem?
