Perhaps Apple has been allowing more inter-process thread mixing as the OS increases in complexity.I don't have a solution for this one, because I don't know how one would tell if the file is in use by another process, and we wouldn't know how long to wait for it (it could be forever, as in the case of SimpleText locks).Grant Hulbert, Director of Engineering ********************************** Smith Micro, Internet Solutions Div | eCommerce (WebCatalog) 16855 West Bernardo Drive, #380 | ------------------------- San Diego, CA 92127 | Software & Site Development Main Line: (858) 675-1106 | http://www.smithmicro.com Fax: (858) 675-0372 **********************************############################################################# This message is sent to you because you are subscribed to the mailing list .
