Hi,
i had the problem that the Pet Battle Highlight Texture was to Big. So i edited the "Skins/PetBattles.lua" File and added at line 487:
Lua Code:
bu.SelectedHighlight:SetDrawLayer("BACKGROUND")
bu.SelectedHighlight:SetPoint("TOPLEFT", bu, -7, 7)
bu.SelectedHighlight:SetPoint("BOTTOMRIGHT", bu, 7, -7)
Hope this helps.
