[Solved]Can't input anything until the source code file is saved

[yaoyansi]

Hi all,
I encounter an annoying problem when I edit my source code file in C::B. Sometimes I can't input any letters into the source code file until I press Ctrl. I don't why.
Could you give me any clue?

BTW: my system is Centos7 x64, and the information of my C::B is:
version: svn build rev 9857,
SDK version: 1.23.0


Regards

Thank you for your reply. It is solved.
I use Centos7 and install a Chinese(Intelligent Pinyin) Input Sources.
This problem disappears after I switch my input source to English.
