Scripts used:

onLoad:
local myPanel = self
local otherPanel = PitBull4_Frames_target
if otherPanel then
  otherPanel:SetScript("OnShow",function(frame)
    myPanel:Show()
  end)
  otherPanel:SetScript("OnHide",function(frame)
    myPanel:Hide()
  end)
end
if otherPanel:IsVisible() then self:Show() else self:Hide() end

After setting up scripts and clicking Accept, everything goes well... but after a reload nothing happens if I target someone.
