I recently got a new computer (running Vista 64-bit). After calibrating the monitor (HP LP2275w calibrated with a Spyder 3), the next time I booted the computer, I got the message "Adobe gamma loader has stopped working". Didn't surprise me too much, just thought the new profile had turned it off, so I disabled it (Adobe gamma loader, that is) in the startup programs so as not to get the annoying message each time I started the computer. Next day or so I checked calibration, to find that the gamma was now way off. So, my question is: Should Adobe gamma loader be on or off when profiling the monitor? Or does it matter as long as it stays one way or the other? And if it should be on, why would it have stopped working and how do I correct it?
