Where would we be without Oswald and Kay, they are always at the cutting edge.
Just installed php5xampp-dev on Server 2003, a few problems trying to get Apache to run, in the end I copied and modified the old WAMPP batch files and from then on no real problems.
All my old web applications are running faster.
My PHP/MySQL development package also worked perfectly so everyone has done a super job on backwards compatibility.
Very best wishes from the UK, Steve...
