!!!! I just discovered a new twist to this litte problem, I should have tried it earlier but didn't think of it (sorry!) The link at the top that says 'delete' works fine, it's the link at the bottom that is screwed up!! I *just* tried the top one and it deleted that list perfectly, then using a new list I tried the bottom link and got the same error as above... Please let me konw if you still wish access to the installation. (you might be able to reproduce this one now :-)
sorry to be such a bother
