[vbox-dev] regression - changing NAT to Bridged breaks 3D aero Win7 theme

[quickbooks office]

When the VM is running if I change from NAT to Bridged it breaks the
3D Windows 7 Aero theme.

I usually need to change networking situation of a live VM i.e. NAT to
Not Attached (to disconnect internet access etc.) or NAT to Bridged
(to print etc.)

I don't know which VBox version introduced this bug. Would appreciate
if a dev can take a look into this.

Thanks.
