I have created a new Flex project that contains an mxml file. I have specified the dimensions of the file in the <mx: Application> tab.
However, once I export a release build and run the swf file on its own using Flash Player 10, it opens in a funny default size and I have to drag the window to the required size.
The solution is probably simple but I have been searching for it without any success. Any help?
As you have mentioned the solution is simple:
Since it a flex project you can add a metadata in the application file as shown below
and build the application now you should have an outout SWF with dimension you have specified.
Most of the time the application SWF should be accessed using an HTML wrapper file, and you can use the default one Flex Builder creates for you or you can roll your own:
