Nice one, Kay... One step further: Why not automatically "maxReadSpeed()" as part of the LC's startup routine? Richard gets his buffer size, Alex gets his simplicity, and you can have the kudos :) Hugh Senior FLCo _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
