I think im having a similar problem as far as data not available about the party when you reload in a party/raid . My post here though is to point out that secure code can be used to move frames when you reload in combat and unless a frame you are moving is a blizzard frame tied into the blizzard frame management system, combat should have no effect on its sizing or positioning.
My problem with my own interface which i think has to do with party data not available right off the bat after a reload
