I'm having the preview screen problems mentioned above, and another, more serious problem, which I'm not certain is related to the Mac OS upgrade or not. My mailing usually takes about 8-9 hours to go out. I'm now 36 hours into a mailing and it's only about halfway done. I haven't changed my MaxBulk Mailer settings. My internet connection seems fine. I've paused the mailing and rebooted my Mac just to be sure it wasn't anything to do with my computer. Has anyone else experience a major slowdown in MaxBulk Mailer since upgrading to Mavericks? Or should I be looking elsewhere for an answer?
Thanks in advance for any clues!
