My iBook has a problem. As evidenced by the title, the spaceb ar on it acts a little crazy. If I type a space, sometimes it only hits the spac e once, but other times it hits the space two or more times. I'd like to know if there is a n easy fix for this that would not involve buy ing a new keyboard. It doesn't matter if it's a utility or a hardware mod. Thanks for your help, whoever responds to this.
