Probably an old question, but I didn't find anything useful by searching the group.
I'm using the trial version of Flex Builder 3 Standard. I create a new Flex project, and, without writing any code, export a release build. The swf file size is 147KB. Then I create a project that contains nothing but an empty DataGrid. The file size grows to 242KB! Throw in an AdvancedDataGrid, and it's up to 300KB. Is there anything I can do to reduce the size? Even 147KB seems huge for an empty app. And why does DataGrid pump it up so much? I heard that the Flex framework was included in the Flash 9 runtime. If that's true, adding a DataGrid should have no effect on output size.
