Possible memory error source

[meganbkratz]

I was starting my second slice, so already had a bunch of windows open (prot. runner, patch, data manager, analysis). I was making a grid and dragged it over the corner of the camera region. I may have accidently clicked the corner of the camera region instead. But suddenly everything locked up, and I got this message:

Traceback (most recent call last):
  File "C:\Documents and Settings\Experimenters\luke\acq4\lib\devices\Scanner\ProtocolGui.py", line 652, in rgnChanged
    self.regeneratePoints()

    self.points.append((x, y))

Is this bug reproducible? My best guess based on the backtrace is that you
somehow ended up with a very large grid (due to some error in resizing?) and
filled up memory creating all of the targets. ..but if it's not
reproducible, then there's not much we can do.

Hmm, I didn't check cause I had a cell at the time. I'll check monday. What
happens if you make the camera region larger than the 512 X 512ish region?

You can't. If you could, I don't know what would happen.
