[Scilab-users] Long delay before callback

[Stefan Du Rietz]

Stéphane, thank you very much for your example!

However, everyone of my callback functions is short-lived: it just does 
a few things and exits. Sometimes the response is instantaneous but 
sometimes it takes a long time. I have not so far managed to notice any 
pattern in that.

Stefan
