seems that way... only issue i'm noticing is if your taskbar is set to always be on top (most have this set by default), then if you fullscreen something on the primary monitor (with taskbar) and click on something on second monitor... the taskbar comes up in front of the video. The video stays full screen, but the taskbar pops on top. Doesn't matter what you click on the second monitor.
Setting taskbar to auto-hide seems to resolve the issue (minus a single pixel line where the taskbar resides at the bottom). The option to disable always on top in Windows 7 was removed, but there are hacks to get it back.
