Sandro Martini updated PIVOT-860:
---------------------------------

    Attachment: pivot_kitchensink_expanders_profile_test_1.png

Show top methods used during Navigation (containing more Expanders) displayed. 
Could be some infinite loop to cause this.

> When displaying an Expander component, the CPU usage immediately goes up and stays at
100% as long as the component is displayed (even if the window is background, reduced or whatever).
> To be precise, I really had 50% because I have a dual core : one of the core was 100%.
> Reproduced on 3 different computers, all Windows XP, with Java 6 and 7.
> Reproduced in applet and in standalone application shape.
> Steps to reproduce : 
> 1/ go to http://pivot.apache.org/tutorials/sample-application.html
>  -> CPU is normal, say 5%
> 2/ click on "navigation" to see the expander
>  -> CPU is at 100%, at least one of the cores.
> Alternative : just go to http://pivot.apache.org/tutorials/expanders.html and expect
the same.
