Hi John,
Thank you for informing me of this. I didn’t realize I need to be opted into the beta releases and didn’t even realize that the version number you provided wasn’t the same as the most recent. I downloaded the 4.00.051 version and it does seem to fix the problem. There is still a minor issue. After printing a Fedex with shiprush the “Print Postage and Carrier Label” sixbit window lingers indefinitely. I have to manually click cancel or X to close the window. In previous versions the window will automatically close after the label has been printed and process.
