Hi. I'm triyng to use the profiler, but such strange thing happens: the debugger runs ok, but the profiler button never goes activated, and when it was, clicking only brings "no profile data available yet" blah.

Of course at the time I click, the code already ran over a couple of functions, so, where is the data?

I'm using version 3.2 - 3217 at work. phpinfo() shows everything just like the FAQs.

What's wrong?

Since version 3.3 you have more control on whether profiler should run with debugger or independently. See tools->settings->debugger-> "Run profiler with debugger".
You can always run a profiler session (instead of debugger session) by clicking on "E" alike button on the toolbar, see "Run profiler (Alt-F9)" description.

This button is always disabled.

I said since version 3.3.
If you run 3.2 you can see profiler charts only during debug session when it stopped and waits for the next step.
