Java applet does not work for specific users

When java (1.5 update 5) is installed as administrator, applets work properly for all users and power users except 1 particular user on some computers. For the user in question, all permissions and profiles are the same as any other user, but java will not work.

An uninstall/reinstall as administrator does not resolve anything.

the only fix we've found is to create a local admin account for the specific user, uninstall/reinstall java, then remove local admin account. After that, java works properly for all users.

What could be causing this issue? We'd like to prevent this from reoccuring
