Avatar hang up when trying to talk to others by pressing 'e' while moving without cursor

When you are moving and the cursor is hidden by 'TAB' key and you are trying to talk to others by pressing key 'e', you will arrive at a situation that the conversation dialogue will show up and no cursor on the screen and you cannot do any typing. Basically, you are hanging up and cannot do anything at this situation.

I have report this bug several times in the past release. This is going to be a very bad user experience especially for new users.
