At least on my computer, this seems like a real POS of a release.
What are your system specs, Mark? I just selected 12000+ CogoPoints, although it did take 30 seconds, or so, to do so and may have appeared to be in a loop (selected these by window). But this is about the same as 2012. I will say that I'm not using 2013 for production due to compatibility with others I need to work with.
My computer has some kick-ass specs unfortunately its still running XP. It was spec'd out, and came with Windows 7-64 bit but they took it off and installed XP.
No, this was a loop, with text spewing across the window.
