Oh, I was also going to point out that a simple .wrap is probably what you want there, rather than screwing around with overrides that depend on clobbering the class or on type changes getting propagated to existing variables. Of course, a .wrap could be construed as clobbering the class, but if you don't want to change the underlying functionality, it's a lot cleaner than replacing the method in question. Larry
