Thanks Greg! I've added a 10.5-only leak. Alas, we only get a report of this every few months or so, but hopefully I won't see it again. I suspect this is probably the issue however, for one thing, most of us in the office do not have mics, so our users test this way more than us. Thanks also to Bill and Jens for their replies. For the record, I don't use NSMessagePort nor Distributed Objects, nor do I do any dynamic loading nor unloading of bundles.
