Hello Andreas,
Thank you for detailed explanation.
However, I am not able to do what I want. Almost.
I have discovered, that if I use only CA layers transformations (via
setTransform:), I am getting the same rotated pixels when zooming in.
The only way, which does what I want is:

Another issue with this line is that, assuming 'gameColumns' is an instance
variable of the object, the array will be autoreleased, leaving the variable

Ok, I have found, in order to use QTMovieDataSizeAttribute I must set

QTMovieOpenForPlaybackAttribute is YES I can't access the Movie variable, as

and I need the mMovie variable, e.g. for

This is the correct behaviour (at least from Core Data's perspective). Undoing
registration effectively amends changes onto the previous change. It doesn't
remove the changes entirely from Core Data's notice.

You don't need root, you need to force Finder to re-read the file, which you

This works fine the first time I run it. The second

I have completely commented out all the actions of the method that is executing
in the thread. The only things it does are to create an autorelease pool, call
a simple performSelectorOnMainThread, and release the pool. There is nothing
else going on that I can see, and yet it still fails as per

Umm, as I mentioned, I have stripped back the multithreading part to virtually
nothing and taken that code to a test application and it works there, and the
rest of the application is 23,000 lines of code, which I can't post.
In my main application, the following still fails (workerThread is an
Some thoughts:
1. What happens if you specify a different object to receive the
message? For example, try [NSApp performSelectorOnMainThread:
@selector(terminate:) ... waitUntilDone: YES]. Does your app
terminate?
2. Specify waitUntilDone: NO, and after the call to
-performSelectorOnMainThread:,
Also: a quick peek at the assembly of -performSelectorOnMainThread:
reveals that it calls _CFExecutableLinkedOnOrAfter(). Presumably this
is to modify its behavior based on what SDK your app links against;
perhaps changing your Base SDK has an effect?

Interesting:
1. No.
2. No.
Weird...
Now I thought it would be interesting to try those calls before the thread was
dispatched, and the terminate one worked, but the run loop stop didn't. I also
tried the runloop stop one in my mini test application, and it didn't work
there either, so am a bi
I have copied the source code to a different computer, and can confirm that it
made no difference - the behaviour is the same.

Thanks for those excellent suggestions Dave (way above my head, but it's good
to have the instructions to execute).
1. Current mode is kCFRunLoopDefaultMode
2. Nothing beginning with NSThread (same was true of my mini test app)
3. Yes, it broke at both those points, and there was something odd go
