When I create a new host only network adapter, it will not set the IP address I assign to it. After I save the IP address & netmask it looks like it works (I see the Windows 7 User Account Control verification box), but the IP address doesn't get stored on the adapter.

I have tried adding/removing the adapter from within virtualbox and settings the values manually in the Windows aapter settings dialogue.

I am using a Windows 7 host.

Does anyone know why the settings don't get saved, or how to get more information?
