When I am logged in with user rights Internet Explorer (version 8 running under XP, SP3) is very slow. It can take tens of seconds to load a page and sometimes IE even hangs. However, when I am logged in with administrator rights everything works fine. How can I get ZA working properly under user rights?
(Note: I know that ZA causes the troubles because when I switch off ZA IE8 also works fine under user rights).
