Nvida Surround gives problems with spanning taskbar.
TL;DR Nvidia Control Panel (8.1.760.0) and Nvidia surround are crap for me. Taskbar doesn't stay still and unbearably long waits for selecting options in NCP.

Win8.1 64
3 screens (1920x1080) -> 5760x1080 3xDVI
I have two GTX 660's. I have them setup in surround and I have one (virtual) large screen with one long taskbar.
The taskbar will randomly switch to span just the middle screen. Start button and clock on the middle screen. If I go and click on the taskbar or any program pinned on the taskbar, the taskbar will switch back to span all three screens without launching the program selected, so I have to click to make the taskbar large then follow to the left screen and then click to open the program.
Then within 30-45 sec the task bar will revert back to spanning just the middle screen.
I have seen videos of opening the Nvidia Control Panel, selecting the Desktop -> Surround Display -> Confine to Center Display I do this to no avail because the NCP freezes and does not respond for 20-30 when selecting the Desktop menu option and then freezes again when hovering over the Surround Display. Then exits the options menu not letting me select the option to confine or not. (selecting File, Edit, 3D Settings, or Help NCP responds normally)
I have a 15 min video of me trying to show the taskbar reverting and the troubles of the NCP. It's so long because I was also showing the issue of me right-clicking on the desktop to get the NCP menu option which would take 45-1.5min for just the right-click menu to pop up. I would upload it but don't want to take up space on the interwebs for this crap. When I recorded the video it let me get to the Confine option (it was checked). When I supposedly unchecked it, the taskbar behaved the same as before.
I have used DDU and installed the latest 347.52 drivers without 3D stuff and without Geforce Experience. And now i have to find the workaround I found to get nView to install again (a cool Nvidia business class program to setup up multiple virtual screens on each monitor)
I just ran over the free trial of DisplayFusion and like the three taskbars but not the taskbars over fullscreen windows and games.
