Stephen, It certainly sounds like there is a bug within the Scientific Calculator based on your extremely thorough and detail testing. I think it would be great to send the below report to [email protected] to allow for the Support Team to verify the issue, submit it to the Trac' database and for it to hopefully be fixed during the KeySoft 8.0 Beta cycle and to be fixed in time for KeySoft 8.0.
