Hi Craig, I just noticed a new top bug and prepared the attached patch in case you wish to swat one more in release 3.3.3. It's not a "letter of the law" fix, only a "spirit of the law". I have an alternate patch that actually changes the program and documentation to conform to the IEC binary standard, but it's feels premature given the slow adoption of those conventions. Regards, Jim p.s. hope you don't find the commit message too offensive...
