This tip may sound funny for must of you but it was a discovery for me.
When I used the “color picker” in Flash, I always thought that I can only pick colour in the Flash application. But in fact, you can use the color picker in all your screen even if the cursor icon of your mouse change like if he wasn’t listening to the flash application anymore.
So this is the tip :
the flash color picker Tools works in all your screen wide and not only in your flash application.
I hope that I wasn’t the only one to be unknowing that one.
