I am doing a website for a client in Flash and the document fits in my window, but not the clients. I changed the size and still have the same problem. I do have animation coming from the outside of the box. Could that be the problem?
You have to force your application to resize based on the client's resolution. This means you will have to make it to dynamically adjust based on the resolutions of the users computer. You can use the tutorials available on the Google Search websites to get an overview about the code you have to use to dynamically resize the content based on a computer's resolution. Try telling your client to switch the resolution to something bigger.
