    Have a brand new 2009 MacPro with 2 video cards and 3 monitors. The following two things (so far) do not work:

    Aperture, when secondary viewer is enabled.
    Powerpoint, when I view a slideshow, which uses two screens by default.

    Both work for a few seconds but then the application freezes, and in some cases I can not force-quit my way out and have to hard reboot.

    Anyone out there with at least 3 monitors been have/have not had similar problems with two-screen full-screen applications?

    I have a 2008 mac pro with 2 cards and it lags on screen savers, kind of like what your taking about but my problem involves screensavers. I found that 2x2600s fight with each other. (i used to get a problem where only one would turn on, reboot, and they would switch, the one that just worked wouldnt turn on but the other would.)

    Let me also add that use a program that I wrote that uses a OpenGL shared graphics context among two windows (which share the same textures), and this program happily works no matter which two screens I put the windows on. However, this is not full-screen mode unlike Aperture and Powerpoint.
