I've recently seen the class being used in the wild so I guess it was time to properly publish it.
Since the beginnings I've always had a
FPS meter class, really basic, but had to be there. Then
Carlos came along with one with a nice visualizer of the performance and then I saw
Alternativa's one and I though that was the best approach. However, it had some issues, the speed of the graph seemed a bit pointless as the history was of 1 second or so.

So I improved my own one on the direction of the latest, but having a graph history of about 10/15 seconds, having a clearer picture of how your app/site is performing.
Theo came along and helped with the graph visualisation too and then it went public.
Anyway... if you need a tiny and easy
FPS/MS/MEM control panel, feel free to use it :)

I find this class super useful, so first of all, many thanks.
Now I'm trying to use it for a new project in FP10, but Stats doesn't seem to work properly. The texts freeze immediately, while the graphs keep running. Targeting the SWF to FP9 and everything is fine again (too bad the project needs FP10).
Any idea why that is? Anything I might have missed and should check?
I'm using FlashDevelop 3.0.6 and the Flex SDK 3.5.0.
