Right. But Jens had had: > attributes = [[NSMutableDictionary alloc] initWithObjectsAndKeys: > NSFontAttributeName, [NSFont fontWithName:@"Helvetica" size:75], > NSForegroundColorAttributeName, NSColor redColor], > NSShadowAttributeName, shadow, > nil]; -- i.e. key, object, key, object; this is what I tried to correct this in my post, as shown above.

But that's not what Jens had posted, which is why I jumped in. (Note that his $dict utility function does have object, key, object, key.) -- Russell _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
