Hi I'm hoping someone can help me. Up until recently I had no trouble with my imac or my mail program. I recently upgraded my operating system to 10.6 and still no problems. The last few weeks though I had constant problems with my mac shutting down with no notice or just freezing. I finally reinstalled the operating system and things are working ok again, or so it seems. Before I couldn't even get into my finder. But mac mail is no longer allowing me to reply or send. I have checked all the settings and they seem to match everything I see online for what they should be but pressing reply or send does NOTHING when I'm in mac mail. I know I can use my ipad or web to send mail but would really love to fix this, I just spent the entire day trying.
