If I executed my App with perl and there is a console window 
opened for it not. Maybe if I use wperl (which do not open a 
console), then the executed script opens a new console window,
but I'm not sure. 

So it looks like I have to differentiate them by Process Id 
and the timestamp, when they where executed. It isnt that kind of problem anyway, it would just be better if.

Thanks anyway
