Hi,

I use multiple custom classes like tweenlite, csvparse, papervision and many more. The way I do is put them in one central location and edit Flash CS4 Actionscript 3.0 settings to include that location.

The problem I face is even though I don’t use all the classes in a project, flash CS4 compiles every single class that is in that central location eventually increasing my compile time by minutes.

Is this normal or am I doing in incorrect way.

Thanks.
