parental controls unstable
I administer an account with parental controls set to restrict web and application access, and interface customization. (It's for a very young child).
It seems random whether the parental controls work or not. Most of the time, they do work, but only some of the allowed applications run. Most don't get proper icons (just the generic dog-eared page), which is a serious problem for pre-literate, illiterate and poor-sighted users. Some, like PhotoBooth, won't run at all.
Occasionally, the app restrictions disappear, and the child has access to every app. At the least, they all get their icons. But they shouldn't be appearing at all.
I've checked the account pref settings over and over, and found nothing that looks wrong.
Where else should I be looking? Are there some known causes that are likely to be behind this?
My admin account on the same machine is working just as I'd expect, no problems at all.
