    Hi,

    I have a mid 2010 17" MBP and two of nearly identical dell 24" monitors over mini display port to dvi adapter, one @home and one in the office. Everything worked fine until recently (shortly after 10.7.2).
    Since one week I have problems when switching monitors. When I'm plugin-in 'the other monitor' (from work to home or vice versa) the colors on the external monitor are gone. Mostly to see in dock (cmd-tab clicking produces white icons), photos are reduced to base colours, etc.
    Funny thing is that if I move a window (for example thunderbird from native to external) it looks ok on the native display, but the half on the external monitor is white with pink lines).
    After a reboot the problems are gone, until next monitor switch.
    Anyone else having the same issue? Does it sound like hardware or software problem? Anything one can do against it?
    thanx in advance!
