I've tried printing a shipping label on my MacBook Pro in 3 different browsers (Chrome, Safari, Firefox) and each time nothing happens. I do not have any pop-up blockers turned on. I've been using this service for years and periodically have this problem. I cannot seem to determine when it works and when it doesn't! Any ideas? Meanwhile, I'm trying to use my old PC with IE, but it's being stubborn and won't go to the details page so I can reprint...arrrgh. If all else fails, I guess I'll cancel the label and go directly to the USPS website, which generally works well from my MAC. It's just frustrating that this service, which is supposed to save me time, is steeling an hour, today ;-(
