Eyegaze limitations

Hi all,

I recorded a character's eyegaze for a 7 minute recording in one take using keyboard input.  Upon reviewing, I identified that I needed to re-record several areas in the timeline.  I was able to make short recordings to the eyegaze (3 to 7 seconds) the first two times and position those recordings in the timeline appropriately.  During the third instance, I recorded, but no bar appeared in the timeline.  Upon replaying that section, the original eyegaze positioning was shown and not the newly recorded one.  Since I am not seeing any changes in the timeline bar, I am wondering if there is a limitation to the number of eyegaze recordings one can take, or am I missing something?
