I would like an answer to this as well, although I don't use a KVM i can see that my problem is closely related and a fix to the KVM-problem would solve my issue as well I'm guessing.
My issue is that every time i turn my monitor off, Windows 7 rearrange and resize my desktop windows. This probably happens because win7 change the resolution of the desktop when the monitor gets 'un-plugged' (in reality just turned off).
This is pretty much the same thing as all the ppl above me are describing, windows 7 is messing up screen resolution when it detects hardware beeing switched arround. A very simple fix to this is to turn that off! As described above, this can be worked around by minimizing all windows before i turn the monitor off, which lead me to the conclusion that it should be an extremely easy thing to fix.
Please give us the option to turn the automatic screen resolution change-thing off.
I agree. This is the kind of thing that must be controllable by a registry setting somewhere. Help!
