Kristof,

Thanks, this is exactly the answer i was looking for. What if, let's say, a
user didn't go to 2003 (because whidbey was all ready on the horizon and is
promising to not rewrite my code) and is still using the original. Is there
work arounds that do the same thing for 1.0?

thanks a ton for your time

Steve
