With the dev tools open, if I open the Systems screen and move the slider, then mouse out and back in, I see this problem.  It happened 2-3 times in a row so I thought I should report it:\r\n\r\n> Uncaught Error: Assertion failed: Exit events not matched by an enter\r\n\r\n![image](https://cloud.githubusercontent.com/assets/679486/9190903/659c9ed0-3fb8-11e5-832e-fd926e3e670c.png)\r\n\r\nI'll reassign to @pixelzoom to see if he can reproduce the problem.\r\n\r\nI'm on OSX 10.10.4 running Chrome Version 44.0.2403.130 (64-bit).
