Would someone do my a favor and run the following line (by itself) in a blank document compiling for Flash Player 10 in Flash CS4? I don’t have CS4 yet, but I didn’t think that it would be worth downloading the beta just to check this one thing.

```auto
use namespace virtual

```

Does that line fail silently? It should also fail if you use `native` or `intrinsic`, since these keywords / future reserved words cause weird behavior with Flash CS3 and the Java version of ASC. Thanks! :love:

Note: If you use any other undefined namespace there or declare the variable first, you should get a compiler error.
