@vylc Do you mean it froze momentarily or permanently? I tried recreating on a fresh install and it took a second but it more or less worked as I expected. Can you provide more info?

Is this a perf issue with lots of values? What's your row limit on this one?

I have experienced this crash but only temporarily @jeffcarey I am looking into the bug with the chrome developer tools profiling.
