How to undo "autoscale" mode?

[n2j7]

I have a Virtual Machine with Windows7 (Guest OS) with installed Guest Additionals.
Once when i doubleclicked into my Guest OS - VirtualBox asked me something like "Switch to scale mode?".
And I answered "Yes" with selected checkbox like "remember my decision"

At now when I doubleckicked anywhere in the Guest OS VirtualBox toggles scale mode!
So, how can I switch off this behaviour?

I want to run Guest OS in a window and never switched into scale mode.
Something like: "Switch to scale mode?" with answer "No" and selected checkbox "remember my decision"

Host(R.Ctrl)+C will exit from Scale-mode

Do you read my question??? Maybe I wrong explain my problem...
I know about Ctrl+C, but how can I disable this feature(shift into scale mode)?
Or how can I recover the dialog where VirtualBox notified me about going into scale mode?

My problem is that when I doubleclicking into Guest - Virtualbox without any notifications goes into scale mode!

You can re-enable *all* questions, not just this specific one, by doing Help->Reset All Warnings
No way to do this for one specific question.

Thanks! I've encountered the same behaviour and was looking everywhere for a way to re-enable warnings...!
