I moved from MobileFrames to use Visor2 and NDragIt. I also grabbed the Visor2GUI to aid in setup of the frames. I used the GUI to set new position for alot of frames. Frames like, character window, talent window, inspect, dressingroom, quest log, merchantframe, gossip frame... etc.
The problem that I am having is that some frames are not being saved where I place them with Visor2. I will use the GUI to set the new location and hit done. Close the frame and reopen it. It works fine. Continue playing and it works perfect. However after a logout the frame goes back to the default location. If I open Visor2 it still show the new location I set it to. If I open the GUI and set one of the X or Y locations the GUI will fill in the other from Visor2 but it will start with the default location X and Y. I do use mods that modify some of the frames I am having trouble with, like the quest frame. However, frames like my talent frame I have nothing that modifies it and it continues to reset even though social and character frames are perfect.
Frames that reset: AuctionHouse, AuctionHouse dressingroom, inspect, talents, questlog
Frames that are fine: character, social, spellbook, dressingroom, gossip, merchant
