Re-opening in the same position it was last should work, although I am not really sure how it behaves with two monitors (I only have one). Could you please move HoDoKu to your second monitor, save the current configuration to a hcfg file and post it here along with the resolutions of your screens?

Hibernate: I never thought about that, I will have to investigate a bit further on this, e.g. I dont know which events (if any) I receive after the computer wakes up again.
