Ok, Art just posted this on the Yahoo group_
Hi Ron:
I gave this a top priority, Id like to get the G41 as tough as I can. Version .048 fixes this problem. It turned out to be the same square root error as before, only in a slightly different way. I have tightened it up a lot, so this can't or shouldn't happen again . Thanks for the bug, download .048 and that arc will work fine..
Art.
