Problems with viz.screencapture

[jrodman]

I'm having some problems with the viz.screencapture function.
1) When it captures an image, it captures it upside down (reversed up and down, but not left and right).
2) If the Vizard World Window is resized, it contiues to display the world as you would expect, but if you attempt to call screencapture after resizing it, the program crashes. It says that it's genereating a log file, but I cannot find one. (If you resize one dimension at a time, it still works. It only crashes when you resize both dimensions at the same time.)
3) It captures whatever is on the screen in the area where the Vizard World Window is at the time screencapture is called. This means it can end up "capturing" pieces of entirely different windows if they're on top. This is easy to work around, but it doesn't seem like the correct behavior.
