在Publish settings->Flash->Version改成Flash4，然后发布就可以了。Flash会自动把Flash5的语法改成4的。(不是所有都可以改,参考下面所说的！)
Using Flash 5 to create Flash 4 content
If you are using Flash 5 to create content for the Flash 4 Player (by exporting as Flash 4), you won't be able to take advantage of all the new features present in Flash 5 ActionScript. However, many new ActionScript features are still available. Flash 4 ActionScript has only one basic primitive data type which is used for both numeric and string manipulation. When you author a movie for the Flash 4 Player, you need to use the deprecated string operators located in the String Operators category in the toolbox.
You can use the following Flash 5 features when you export to the Flash 4 SWF file format:
The array and object access operator ([]).
The dot operator (.).
Logical operators, assignment operators, and pre-increment and post-increment/decrement operators.
The modulo operator(%), all methods and properties of the Math object.
These operators and functions are not supported natively by the Flash 4 Player. Flash 5 must export them as series approximations. This means that the results are only approximate. In addition, due to the inclusion of series approximations in the SWF file, these functions take up more room in Flash 4 SWF files than they do in Flash 5 SWF files.
The for, while, do..while, break, and continue actions.
The print and printAsBitmap actions.
The following Flash 5 features can't be used in movies exported to the Flash 4 SWF file format:
Custom functions
XML support
Local variables
Predefined objects (except Math)
Movie clip actions
Multiple data types
eval with dot syntax (for example, eval("_root.movieclip.variable"))
return
new
delete
typeof
for..in
keycode
targetPath
escape
globalToLocal and localToGlobal
hitTest
isFinite and inNaN
parseFloat and parseInt
unescape
_xmouse and _ymouse
_quality
