I'm trying to get the CPU Profiler tool in Chrome to work and I'm seeing
some odd behaviour. This was working for me earlier today. I was able to
get a cpu captured and navigate around the various call stacks no problem.
Then it stopped working when I did something more DOM-intensive and now
even my simple case doesn't work any more.
Basically, what happens is after the profiler stops it displays a list of
functions in the "bottom up" view. When I click on the arrow next to any
of the functions, the first click does nothing and then the second click

function. Sometimes there are "self" and "total" numbers next to the empty
lines and sometimes not.
Same thing when I switch to "top down" view. First click on a function

should I file a bug?
BTW, I'm using Version 22.0.1229.79 m on Windows 7 64-bit.
