Some Problem with C includes

[NEX-S]

when i programming in C, I've found that once I enter include, the cmp gives me a hint include <header>, after I confirm select and write the .h file that i want, i can't just use > to go to the next position... for example: | is my cursour position, i want to hit > in include <stdio.h|>, and got include <stdio.h>| in " circumstances, every things seems to be fine... include "test.h|" and hit ", include "test.h"| is this cmp problem? i dont know how to fix this small problem :(
