Κeyboard problem in B7300XXJC2

[Guest NeTo3]

Hello! I installed the B7300XXJC2 ROM. The phone is faster than before the update, but there is a problem. When i write an sms on the keyboard, not the qwerty but in the keyboard like the numpad, i must wait to "decheck" the letter i wrote, and after this press the next letter. What can i do to solve this problem? Sorry for my english
