Mail canceled shutdown (10.6.7)
I'm running a late 2010 model iMac i5 running 10.6.7 and Mail v4.5. I've had this computer for several months but am now using the Mail app for the first time. I have found it to be very useful in managing my multiple email accounts and I would like to use it from now on.
My only issue is that whenever I try to shut down my computer, it fails to do so and I get the message "The application Mail canceled shutdown." In addition to issues shutting the computer down manually, I believe it also prevents the computer from going to Sleep. I set my computer to Sleep after being idle for 30 min, however all that happens is the monitor shuts off/turns black, but it does not go to Sleep. The computer does Sleep if I press the power button to manually Sleep it, but it will not go to Sleep on its own anymore.
I believe this is all due to the Mail app and I don't know what settings to adjust in order to fix this. I shouldn't have to quit the app just to fix the Sleep problem. That'd defeat the purpose of the auto retrieving of e-mails. Could it be due to the update frequency on checking for new mail. I have it set for 5 minutes, which I believe is the default. I have read other articles on here and online regarding the Mail app canceling the shutdown process, but the solution is to Force Quit the Mail.app. In fact, I have had trouble quitting the app, both manually via Command+Q and going to the Mail menu>Quit Mail.
Is there a way around this so I don't have to Force Quit the Mail app? It seems to be somewhat 'extreme' to have to Force Quit an app just for the sake of shutting down the computer. I can only assume there's a setting I'm failing to see where the app is forcing the computer to stay awake and prevent from shutting down. Or perhaps a bug in the app?
Any info would be much appreciated. Thanks!
