OK, I obviously forgot to add that header to the list (that was  
recently factored from DKDrawing). Thanks for telling me!

At this stage no testing has been done to see if using DK garbage- 
collected just works or if there are issues. So while I see no reason  
why this would cause a problem, it is untested at the moment.

Hmmmm. I have seen this problem when building against the 10.5 SDK in  
the past, though I had thought it was fixed. However, for the moment I  
recommend that you build against the 10.4u SDK. You don't lose any  
functionality at all, but Cocoa on 10.5 will make sure that everything  
is called compatibly. If you link with 10.5 it assumes you are  
prepared to correctly deal with UTIs and other things which, again,  
are not extensively tested right now. I believe this bug is related to  
UTIs but I'm not 100% sure.

cheers, Graham
