I am reviving this thread because I still haven`t fixed the problem. I recently ordered parts from our host from my PC, and I cannot open the tracking update links on my mac either. I agree it could be a dns issue, but I switched to
opendns and that did not fix the problem. I had comcast cable before and all worked fine, now I have verizon fios...it is not a browser issue, I tried them all. My system recently upgraded to OX 1.4.11, but the problem has persisted from the previous version. Any more ideas?
