I apologise if this info is covered on the wiki or elsewhere (if "elsewhere", where?) but I've not been able to find it: In the "client configuration data" dialog (edit/configuration), there are three checkboxes near the top: debug, monitor, and raw blocks. What are they used for? I assume they should be left unchecked for normal use. Also, below those, but above where the "logfile" path is entered, there are two unamed blank fields where strings could be entered. What are these for? I again assume they can and should normally be left empty. - Mike You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat. --Albert Einstein, describing radio.
