Speculation: it might just be an artifact of history, like how -target and -action are on NSActionCell instead of NSCell. The purpose of tag was for the recipient of an action message to figure out which member of a group of controls was actually chosen. Conceptually, senders were going to be NSControls, so back in the day it might have really been a big deal to save those four bytes on each non-control NSView instance. --Kyle Sluder _______________________________________________ Do not post admin requests to the list.
