Aaarrrgggh. I swtiched all my "Disabled in selected applications"
entries back to empty (by deleting them from the Applications field)
in order to try to reenable them. When I quit QS and then relaunched
it, the damn Photoshop entries were all still there,
I went round and round on this, and could not get them to go away.
Finally, I replaced them all with a single character ("/"). That made
them disappear. Then I deleted all the "/" marks, leaving the fields
empty. Then I switched all the pull-down menus to "Enable in all
applications". Each of these with a relaunch in between.
QS triggers are now ALL dead, including the ones I never touched. None
of them work.
I have logged out and logged back in to the entire computer. I
restored all the files in Library > Application Support > Quicksilver
from Time Machine backups. Nothing has worked.
I suppose I have to reinstall QS and rebuild the whole set. Again.
Crap.
