thanks AlfredsDad. i also had to set the "open with" default application to be busycontacts for addressbook meta data found by alfred. i did this by finding a contact and then pressing command to go to "reveal in finder", then "command-I" for get info, and then set "open with" app.
interestingly, the command-o (open in busycontacts) only works when i find a contact and then take an extra step of first pressing return ("view contact in alfred"). from viewing contact in alfred, and then pressing command-o it opens in busycontacts.
but if i press command-o immediately upon finding the contact in alfred, it doesnt open in busycontacts. wondering if anyone else experienced this?
thanks.
