I have been a .Mac/MobileMe subscriber for a long time. But until recently I had never bothered to use any of the services other than mail. Then I started to use my iDisk. Today, I had written a couple of pages of my upcoming book since my last full save and then viola – Word crashed. I’m not used to Word crashing often, but I have Word set to autosave every 5 minutes, so when it does crash I’m not all that overly concerned as the damage is minimized. However, Word was unable to find the Auto-recover location and so was not actually autosaving, nor telling me it wasn’t. So I set the auto-recover to go to a subfolder of my home directory in the Entourage preferences.
Moral of the story: if you’re using iDisk as a save location for Word, check the auto-save location just to be sure you’re covered!
