Ok here it goes. This sounds a bit stupid to me but it’s happening.
Have this one flash site that is on my server. When exporting or running this file it all goes ok. If I copy source fla to some other location and edit it there, then run it or export it it is smaller size and doesn’t work anymore.
This fla is in AS3. It has no files attached or imported and no .as files added.
How is that possible?
