Gianluca , thank, i tried it, i see what you mean . In the capture loop , the UI tends to go dead and unresponsive to clicks and stuff . I think i'll do it the thread way .

not responsive since it's stuck receiving packets in the "onButtonCapture" 
handler...

In any case, I usually prefer not to use "pcap_breakloop". This API is there 
mainly to interrupt a pcap_loop or pcap_dispatch call, if you use 
pcap_next_ex you don't have the problem of breaking the internal loop of 
"pcap_loop" or "pcap_dispatch", because you explicitely create the loop 
surrounding pcap_next_ex.

Have a nice day
