How long was the employment gap? Usually if it's longer than 3 months they may want her to be on her new job for at least 6 months, if the job gap was less than 3 months then odds are it'll be OK without her being at her new job for 6 months.
From the sounds of it her employment should be fine, from your initial post I was assuming the job gap was in the recent past... not 3 years ago.
