Loaded 10.3.7 yesterday. Repaired permissions, then restarted, and virus scan did an update, so I repaired again, restated and loaded 10.3.7. Now mail doesn't work well. My reply button, reply all, or forward buttons/icon don't work. I also noticed a big slow down initially, but things seem more normal now except the performance of mail. Any good ideas? Update: this seems to only happen with some emails, it works on some and not on others.?????????
