flash actionscript: I am getting this error when I check the syntax of one of my classes.

The name of this class, <class name>, conflicts with the name of another class
that was loaded, <class name>

what does that mean? When I run my project everything seems to work fine.

You might have your class files in different places all over your computer and
you might have an older version in a folder that you aren't editing but could
be in the AS2 class path some where. I would recommend have one place for you
code. I have one folder named Classes on the root of my HD and I just put every
class I have in there and all the packages as well. After you can go into you
prefs. in the Flash IDE and under actionscript select the AS@ settings. There
you will be able to select new folders / dirs for the class path, select your
"Classes" folder. So try this and if it still doesn't work you have chosen a
name that Flash is already using. Let me know if you need help.
