no, in fact.
(I should say that I don't recall being the one to put the PCAP stuff in a thread. I have a horror of threads anyway....)
No. I don't understand threads, but I managed to figure out just enough to get them to start in different threads. Obviously, I couldn't then figure out how to make the stop again - you fixed that bit, and therefore claim ownership of that functionality ;-) It may be far less broken than when you first touched it, but you were the last one to touch it...
gah. ok, fair enough.
