Hello.
i have 2 bugs with DF and eyefinity setup.

bezel compensation not activated (i already know that DF does not support it at this time)
configuration :
3 identical monitors (1920*1080)
radeon 7980 in eyefinity mode without bezel compensation activated
1 intel chipset output to TV (4th screen)

1st bug : when my windows taskbar is set to left side on left monitor and DF have split screen activated, a displacement of window appears. the windows are placed x pixels to the left, corresponding to the width of the taskbar.
this bug is temporary fixed if i change some display parameters. but reappear when i restard windows

2nd bug : if i move the 4th display from DF monitor setup, i have glitchs, display drivers crash and i return to previous positions.

that's all at this moment

I Hope bezel compensation support arrive soon.

Ah ! and is there a possibility to setup screen groups for wallpapers ? for exemple with my 4 displays, set a wallpaper for my eyefinity(3screens) desktop, and another one to the 4th screen ?

thank's for the group monitor tips.

1st Bug still exist .
putting a window fullscreen on screen other than the one who have the original windows task bar, 'eat' the left side of the window. the size matche width of the windows taskbar.

another little bug, when activating and desactivating multi-monitor task bar, the space reserved on top and right side of the screens are kept. puting a window full screen let space top and right borders.

temporary fixing these problems by moving this window multiple times on another screens and moving it to it's starting screen fix the problem. but temporary. moving it again and displacment come again.

and a small bug. when multi task bar is activated, sub right clic menus appears on right whatever it's position.and activating multi task bar does not redefine windows sizes automatically. if set to top, top of windows are stuck under taskbar
