Are you two playing on a Mac or a PC?
If you would, open the file [
World of Warcraft > Interface > AddOns > nUI > Main > nUI.lua ] in a plain text editor and look for this line...
Code:
WorldFrame:SetPoint( "BOTTOM", nUI_Dashboard, "CENTER", 0, 0 );
and change it to look like this...
Code:
--WorldFrame:SetPoint( "BOTTOM", nUI_Dashboard, "CENTER", 0, 0 );
then save the file and reload WoW. Does the problem go away?
