Having the 4k option is fine, it's just eliminating the current default which I think is undesirable. I tried 4k stack, I couldn't measure any improvement in anything (as in no visible speedup or saving in memory). For an embedded system, where space is tight and the code paths well known, sure, but I haven't been able to find or generate any objective improvement, other than some posts saying smaller is always better. Nothing slows a system down like a crash, even if it isn't followed by a restore from backup. Feel free to point me at some results showing major improvement from 4k stacks, I'm open to data. -- -bill davidsen (davidsen@tmr.com) "The secret to procrastination is to put things off until the last possible moment - but no longer" -me
