So I have an application that has been bedeviled by a nasty, nasty

Error (1007) creating CGSWindow
At that point, the user has no choice but to reboot the machine -
the Window Server is pretty much hoarked.
You have too many cached NSImages. Because NSImage uses windows to
cache images, and because these windows are a system wide resource
managed by the Window Server, eventually it can no longer create
new windows in any process. The work around is to use Core
Graphics directly, which doesn't suffer from this problem.
Or to turn off caching of NSImages via -
setCacheMode:NSImageCacheNever. Depending on how your using your
images, one might offer more performance than the other.
oooohh... This sounds like a very promising workaround.
I'll give that a shot!
