It did happen to me too, with dictionary attack for testing my wifi.
Make sure there's no empty space after your words in the dictionary.
Backspace all you empty space after each words..(sometime copy and paste will do that, copying the empty space depending how you place your cursor
exemple:
dictionary inside
mao1
mao1mao2
mao1mao1 | <-- blinking cursor (wrong)
mao1mao1| <-- blinking cursor (good)
the save the file
