Hy,

Yes I've got it, that's why I was saying thanks to Taura for her warning
about gtk_main_iteration(). So now I will use it in the calculation
algorithm, and before starting this calculation I'll take a semaphore (you
know this P and V function really usefull to access ressource when dealing
with forks - as I'm not sure of the english word, I hope you understand) to
lock the rest of the UI (or maybe some part only...) and release it once
finished. So I'm just going to build a Macro that will call
gtk_main_iteration() time to time while calculating (and in non heavy calcul
sensitive loop to avoid overhead).
Thanks for your help, it has been really clear and usefull :-)

PS: if I still didn't get it, just tell me :-) but I hope I got it ;-)
