Auto-save only saves as and when it feels like it - maybe once an hour or not at all.

Ugh. Once again, AE crashed, and I thought "that's ok, I have auto-save set to save every 7 minutes". You can imagine my joy when I discovered the most recent auto-saved version was over an hour ago (and yes, I can confirm that auto-save is in fact set to every 7 minutes. I've now changed it to every 4 minutes in case that helps). This happens regularly in the past few beta versions, and does not make for a happy experience.
