I'm guessing that you crash on 10.5/Intel/Leopard/64-bit and do not crash on 10.5/Intel/Leopard/32-bit. If you write anything like this and run on a system where the class is not present, you will crash on 64-bit but may or may not crash on 32-bit: // BAD [NSRunningApplication someMethod]; If NSRunningApplication may be absent at runtime, then you must not refer to it directly, ever. You must use NSClassFromString() everywhere: // GOOD Class nsRunningApplicationClass = NSClassFromString(@"NSRunningApplication"); [nsRunningApplicationClass someMethod]; -- Greg Parker [email protected] Runtime Wrangler _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
