Hello, Peter:
Long ago, perhaps two years ago, I found that using "Area of Screen" for screen captures would sometimes or often lock up my box, so I stopped using it. Instead, I used "Screen", then after capture I'd crop.
Today, I decided to try "Area of Screen" again, and after displaying crosshairs, it locked the box -- the WarpCentre clock stopped, crosshairs would not move, and no obvious response from the keyboard. C-A-D worked OK.
I let it reboot, and repeated the same experiment: same results.
This is quite probably a Matrox video driver issue, but I though that I'd report it anyway. I have several older Matrox drivers, but I've been using the 2.58.144 for several years and it has worked OK for me in most ways.
I do NOT expect you to work around a video driver issue, and I can work around this problem easily by reverting to capturing the entire Screen + crop. My purpose in posting this is to either confirm that this is a Matrox driver issue (so it can be added to the README or Help system), or to pin it down to being only applicable to this particular box.
