Flash Builder 4.6 always shows blank html page on debug or release run

Question

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

Answer 1

Project -> Clean

and check if you are running debug version of Flash Player on the default browser.

Answer 2

right click project name->Properties->select "Flex Compiler"->

there is a label "Additional compiler arguments", input "-use-network=false" in the textbox below this label.

->OK.

Answer 3

Ran into the same issue, the problem being Chrome was my default browser. In the flash builder preferences you can define which browser to use when debuging.
