I explained poorly, verbs in second person are gender agnostic, adjectives are gender-dependent. The "restriced area" is funny, standard version is "Nieuprawnionym wstęp wzbroniony" ~ "For non-priviledged-ones entry is forbidden", it's plural noun made from adjective, in nominative it would be different for male and mixed/female groups (uprawnieni/uprawnione), but fortunately in plural in dative case it's "uprawnionym" for both genders so it works out OK. I guess it's common and maybe that's why the dative case works that way? In most dialogs in software adjectives are the problem, especially "are you sure". Usually software that don't know your gender for other reasons just use male version. In non-software world in formal documents it's often written like "he/she" in every gender-dependent place, often with passive voice to cut the amount of "/".
