I am trying create an actionscript file in Flex Builder 3 and I noticed that
after I put in all my imports and I start declaring variables, most of my
import statements will just disappear. I did some searching on the net and
heard some people mention about using wildcards in there import statments, but
I am not using any wildcards. Is this a function of Flex Builder and if so, how
do I turn it off?

Hi,

You can turn it off. Go to
Window -> Preferences... -> Flex -> Editors -> ActionScript Code

deselect the check box for "Remove unused imports while organizing"

Hope this helps.
