Just encountered the strangest error and want to put it on the list.
Plan to file a bug report about it, although I can't reproduce.
Copy/paste simply stopped working in my application. It continued to
work everywhere else. Relaunching my application did not solve the
problem. Drag and drop also stopped working. Copy/paste returned no
error to the console but dragging produced a "CoreDragCreate error:
-4960"
After some extensive research on Google and the List archives, I was
unable to find a solution that did not require a reboot. One
potential issue was launching the app from the terminal during an ssh
session. I'm definitely not doing that. Another google result
suggested problems with launch services.
I was able to do some debugging before restarting my application. It
seems that calling [NSPasteboard generalPasteboard] returns nil. It's
like my application does not have access to the pasteboard services.
Restarting solves the problem. On the one hand, I want to offer this
up to Fluke, Chance's ugly and less appreciated stepbrother. Reboot
and you're good to go. On the other hand, I have a single user who is
reporting this as a consistent problem. She reboots and a few minutes
later my app loses pasteboard functionality. Other applications on
the system don't seem to be affected, save one which I won't mention.
