I already explained in my previous email. The size is important, and note that (17,10) is the size of the Overflow image I'm using. This makes NSPopUpButton useless in practice for of borderless pulldowns (e.g. Mail's mailbox action button). Moreover, though it works in 10.6.2, it does not in some earlier version (I don't remember if it was 10.6.1 or 10.6.0).
