On my new iMac 21" I get this message when I "wake up" the Mac after a day of non use. It only seems to happen after being in sleep mode for more then 12hrs. I need to re-start each time.

I do have Windows 7 installed via bootcamp.

Any ideas?

Thanks

System Preferences > System > Startup Disk > Select "Macintosh HD" instead of Bootcamp.

Now it'll boot to OS X by default, if you want to use Windows just hold alt/option key during startup. I'm guessing Bootcamp doesn't play friendly with resuming from sleep.
