By the way, yesterday the keyboard was dead during ImageIntegration (or ImageCalibration) too. So, this is not just script related, although there are very few times where a process generates that behavior.
I'm working on a dual 2 core processor, 2 or 4 Gb of Ram. Overall, is a fine machine

Having said that, I think that the monitor is stressing the system a lot, a 30" HP LCD, 2550x1900 px (of curse this is at work, not home! <vbg>)
