Hey. I am writing a program with menu using curses.h. It works well BUT stuck when i add info(e.g. name, author). I rack one's brains a lot but have no idea why it happens.

P.S. interesting thing. If you add after line 60 system("cls"); it will works, but if you add 3 record or more to file program will quit with dump record
And sorry for my bad English.
