    Which "last" was that?
    I'm glad you've solved your problem.  I'm a little concerned with your 
confessed use of "instance variable @found."  Why is "found" an instance 
variable?  It should probably be a local variable and, thus, you'd never 
have to worry about "resetting" it every time...
