I'm running OSX.3.9 on an emac. First, if my Mail program is running while I create a new attachment to accompany an e-mail, my Mail program doesn't "see" the new attachment. I have to restart Mail, then I can select the new attachment to accompany my e-mail. Now, in addition to that, when I open Mail for the first time, incoming messages look fine. But if I go off and do other things while the mail program is still running, and then come back to check out my inbox, I get the following message: "The message from <emailperson> concerning subject has not been downloaded from the server. You need to take this account online in order to download it." The actual message is no longer there. I have to quit Mail, restart it, and then everything is fine again. I don't want to reinstall my original software in order to fix these problems. Does anyone know how to fix them? Or how to reinstall just the mail program? Any help would be greatly appreciated. Thanks!
