I'm having a problem with Flash Builder 4.6 premium. I'm using the 4.6 flex sdk and creating a web application. To test my development environment I simply add: 

```
<s:Label text="TEST" x="10" y="10"/> 

```

between the Application tags of the mxml file. When I switch to design mode I can see my TEST label. However, if a run a debug or a release test ( as web application ) I always wind up with a blank page. I have even tried importing sample code from books that I know to be good code. This is so weird because I have been using the program with no problem for so long then sudenly this. I have blow a whole development day over this.

Please HELP!
Thanks,
Marc
