Hi!Thanks for all your tips. I'll now try it with the sample value of the time between the code is starting and the moment when the user presses the first key. I guess that should be random enough.But, yeah, I agree with Kassen that a function to read the computer time should be included in one of the next releases. It would be much more elegant with that. And of course I am looking forward to the ChucKoo clock...CheersJakob
