She encountered him a few times in cases where all active and reserve Avengers were called in (such as in WCA Annual #1 when an insane Quicksilver betrayed the team and sent the Zodiac against them; or the original Atlantis Attacks crisis, etc). Their first known encounter would have been in AVENGERS #239, after Bobbi married Clint but before she officially became an Avenger, when Panther was one of a handful of reserve members who agreed to go on The David Letterman show with Wonder Man to support his acting career.
I can't recall the two of them ever interacting directly prior to this series though. It was usually just them together in group situations.
