I have a Mac mini 3,1 and I am using Road Runner high speed. At least a couple of times a day my e-mail stops working, I get the spinning pin wheel and a message that my e-mail application has quit unexpectedly and asking if I want to report this to Apple, which I usually do. Then I have to reboot the e-mail. Does anyone else have this problem and is there anything that I can do to help eliminate it?
