I'm seeing a similar problem with Spectraview II v. 1.1.03 (the latest version according to the NEC website) and Windows 7 64-bit that was just installed 3 days ago. It's sporadic though. Here's what I've observed so far. When Windows starts and gets to the login screen, if I wait a bit and don't log in right away, then when I do log in the SV gamma loader seems to run OK. But if instead I log in immediately after the login screen pops up, then during the SV gamma loader's operation the screen goes black and the computer gives a 2-beep error signal. Sometimes it recovers and reverts to the desktop. Other times the screen remains black and unresponsive, and a hard reset is necessary.
As a temporary fix, I removed the SV gamma loader from the Startup folder, so it doesn't run at startup. If I run it manually after startup, it operates normally. So it seems there is some sort of conflict of the SV gamma loader with other startup routines that are not yet finished if you log in too quickly. That's my tentative conclusion, anyway. I would love to hear opinions from some of the more computer-savvy members.
There's a report on
DPReview of the same problem, so a number of us are experiencing this.
