Hi!
I've been using the app in my Nokia N97. I noticed that the same words are automatically added several times but with different punctuation marks at the and.
For example:
word.
word,
word!
To reproduce:
Type the word which is already in the dict (of course using T9). After typing the word do not make any space and when the word is still underlined - press "1" to insert a punctuation mark.
Now use * to change the punctuation mark at the end.
And now you can edit the Custom Dict List and you will find this word duplicated with a different punctuation mark at the end.
The number of duplicates depends on how many times you used the * button to change the punctuation mark.
Regards,
Mateo
