Re: IOKit.framework - The Destruction of my Project

Herb,

Thanks for the reply. I don't even know what IOKit.framework does, so 
I don't call it. The only thing I call is <Cocoa/Cocoa.h> because I 
don't even interlink  my classes together. What other code would 
accidently call or include those two files? And looking into the 
preferences I have no 10.5u SDK references. But if I change it to 10.5 
SDK build target, my only problem is the fact that it stalls (got to 
find that on my own)...

system would say, 'Are you sure?' before going off." - Katie Hafner
