Mail Hard to Open
I'm using a iMac 21.5-inch, with OS X El Capitan ver. 10.11.6, which has Version 9.3 Mail. Lately, I am finding difficult opening mail. I have to force quit several times even before it opens. Its only been happening in the last 6 months. I'm not tech savvy, but can I download a later ver. of Mail. Any Ideas. Thanks Guys
