I use SFFS and it's incompatible with NView. So is winamp it seems (I can't believe a company like nVidia can do a product with this many incompatibilities and get away with it!).
The only think I need NView for is to get a shortcut to flip the screen portrait/landscape.
That should be simple to get with some other tool (I hope!).
Note: there's no tray icon that I can use with some ahk magic.
Since most of you will have NVidia cards, you may have developed a solution.
Thanks
