When I try to start KisMAC I get the following, even though mail,
Boinc and anything else I can think of has bee stopped. Furthermore,
when I tell it to abort, I still lose access to the Airport
hardware. I have to reboot. The implication is it will come back if
KisMAC detected, that there is most likely still some kind of a program, which accesses your airport driver (such as a signal meter, internet connect, another stumbler or a preference pane). If you continue, your Airport Connection might not come back when you quit KisMAC.
Please note on MacOS X 10.3 and 10.3.1 there is a bug in a closed source component of Apple. Please upgrade to 10.3.2 to avoid this behavoir.
