Win XP Pro SP2
Xampp (newest) with Control Panel vs 2.1, PHP vs 5
Installing was a job but now everything is working fine.
I only have a very nasty problem. After starting eGroupware, sometimes, unpredictable, Apache crashes: Apache HTTP Server has encountered a problem and needs to close. Sorry...bla bla bla.
The problem seems to be the PHP-file: php5ts.dll
Thanks a lot.
