Dear Rene Thank you for the fast reply. -Problem 1: I did run make, not gmake, as far as I know this should not make a difference? To run Event, I tried Event Event 400 1 1 (since this was the call in earlier versions?) I will try Event 400 0 7 1 -Problem 3: In my case this worked in version 3.00/01 but not in version 3.00/06 and not in 3.01/02 The reason is unclear to me.
