Hey there, since I got my NFB 12.1 it looks like it prevents my Windows 7 x64 Prof. from going to sleep or shutting down. If I use windows the whole day without powering on the NFB 12.1 then sleep/shut down works fine. As soon as I once power the NFB 12.1 on (even if I power it off afterwards) windows will not go into sleep or shut down anymore.
Anyone has an idea why? Maybe my USB-Power settings on my laptop?
