@property problem

So, I'm trying to be a good little Obj-C 2.0 programmer and use these 
newfangled properties.  Xcode doesn't seem to appreciate my attempts.

I've boiled the problem down to this snippet:

@interface MyWindow : NSWindow
{
}
@property(readwrite) BOOL    capturing;

@end

@implementation MyWindow

@synthesize capturing;

@end

When I compile that, I get the error:

error: synthesized property 'capturing' must either be named the same 
as a compatible ivar or must explicitly name an ivar

AFAICT, "capturing" IS the name of my ivar.  What is it *really* 
complaining about?  What did I do wrong?


Thanks!
