curtor on minibuf after opening file with auto-complete(TAB)

[chuns...@gmail.com]

Hello,

I am beginner for emacs-live.

I am in a very annoying situation. 

After opening a file with auto-completion(TAB), my cursor is still on mini buffer, not on file content.

When opening a file with enter key, it is ok. 

How can I fix it.

Best Regards,

Lee
