Issues with Punch in Punch out

Hi. I have been using cubase since version 4. i have made a zillion punches on audio tracks in that time mostly monitoring through cubase without issue, clean and without any monitoring problems. Now in version 7 the first time i did a punch on an audio track I experience a short lag in monitoring the punch both on the way in and out. When I go back and listen to the punch it’s fine but this issue with the monitoring is becoming a drag. Is anyone else having this issue.
