I have a lot of trouble with string variables becoming "invalid" according to their value in the Debugger. If I set a string variable like NSString *str = [NSString stringWithString:<some other string variable>] it seems OK initially but then when I try to use it later in the program it is invalid and crashes the program. Ususally even tho' the address for the string is the same as before.
