Ok

Computer:

Macbook Pro, 2.16 dual core  
2gb ram  
etc…

I have no other applications running.

I’ve ported my FPS meter in a project and simply just publishing with NOTHING on the stage. On my mac the preview window in flash for the project will run about 1/2 it’s normal FPS until I click and hold down on the panel window bar.

It’s extremely weird and also EXTREMELY annoying. Can anyone else test this and confirm?

Steps to reproduce:

1. create a fps meter or some way to gage you’re fps visually ( ie ball moving across stage )
2. ctrl+enter test the movie… see if the fps seems normal
3. click on the “panel title bar” the top grey strip and see if the FPS increases at all.
