I had my hard drive replaced within the last month. Now I have trouble with the MAIL function. Sometimes it is open in the menu on top, but does not bring up mail. Then it grays out the QUIT MAIL function and I am stuck.
I have problems closing my MAIL. The function of Quit is grayed out. I cannot turn off the computer because it says mail still open. I have had this problem off and on ever since getting a new hard drive and reloading all the functions. The only way I can clear it is to hold the power button down till it shuts off the computer, and then restart it.
