hey,
i could not really get this problem to "work" on my computer. however i
did a couple of changes to macjack, which will do a hardware reset of
the card on unload. (switching off the card and re-enable it). the file
is at <http://www.stud.tu-ilmenau.de/~miro-in/KisMAC005a1.zip>. can you
give me some feedback on this?
this version also enhances the cisco support (you do not have to eject
the card on exit). and also the zoom should more or less stay at the
same point (thanks to ard who bugged me =)
