Copy/paste stop working, drag also, console says CoreDragCreate error: -4960
-
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.
Any thoughts?

It sounds like the pasteboard server on the machine has crashed or
otherwise gone away.
Your user with consistent problemsâare they perturbing the pasteboard
in any way? (Running any custom copy-paste haxies? :) ) Does regular
copy-paste work for them in other apps like TextEdit?

It does work in other applications like TextEdit, yes. It also did on
my machine. It's like the pasteboard server is only unavailable to my
application, no matter if relaunched.
I've asked this particular user about plugins and what not, and she
says no. She's done development herself, so I trust the answer, but
I'll certainly double check.
