To my regret I have noticed the same issue.
I do have the same version installed and have 2 separate harddisks placed in my computer,
Both of them where individually installed with windows 7 and placed in there own bay.
I'd like to have the bootmanager skip the menu unless i need the other install, but i cannot change anything.
When i change the radiobutton to skip the menu and press save it tells me that the settings where saved but when i reboot the menu just appears and when i look to the settings nothing has changed.
I do like the bootmanager as it is very simple to use, but i do find it important for me that the menu can be switched off.
Is this bug being fixed in some way?
Regards John
