I updated PM this morning, and attempted to update the BrowseWithPMService.service file, too (since it seemed to have a newer file date than the one I was using). However, when I attempted to drag the old one to the trash, I was greeted with a message informing me that "The item 'BrowseWithPMService.service' can't be moved to the Trash because it's open." I get the same message when trying to simply copy the new file to the directory where the old one was installed.
I'm running a MacBook Pro with OS X 10.6.2. Any suggestions for upgrading this file?
