I'm still new to mac, so sorry if this is obvious, but...
I have at times installed things, and then deleted them (by dragging them from the applications folder to the trash and emptying it). I thought the applications were gone, but when I upgraded to Lion they show up in Launchpad. They won't run, but either appear with a question mark on them or they give me some kind of message (License expired, for example). Did I leave something on the computer? How do I delete applications all the way?
