When I first tried to use the NSWorkspaceDidWakeNotification and
NSWorkspaceWillSleepNotification notifications I also ran into
problems because I didn't realize that I had to register with
NSWorkspace's notification center instead of the
defaultNotificationCenter:
[[NSWorkspace sharedWorkspace] notificationCenter]
instead of:
[NSNotificationCenter defaultCenter]
Of course your solution has already solved the problem for you, I
just wanted to add this in case anybody else was running into the
same problem.

I've never beeng able to get the NSWorkspaceDidWakeNotification to
work, and I was going to post to the list asking about this but first
did some extra research and came up with a wrapper class that
provides the functionality I was looking for.
Since this may be useful to others, I'd like to share it. The class
also happens to be the first entry in what I hope to be a useful
database of cocoa code that I've recently written.
The class posts a notification when the computer is about to sleep or
when waking from sleep. It also implements a delegate method that can
prevent idle sleep from happening, if for example your program needs
to complete a lengthy operation without being interrupted.
For more info about the class: http://developer.phildow.net/cocoa-

Feel free to use it in any way you can.
