FCKeditor Expert Needed

HI, We are trying to use FCKeditor 2.6.6. We are having trouble with Flash files. The editor is not uploading Flash files correctly. And it looks like the code that gets generated is bad. I believe there must be some fix for this. Here's what I'd like to do: 1. Only allow .swf files to be loaded 2. Make sure that the write permissions to our Flash directory stays turned off until the user is authenticated. Does anybody know how to do this? We need a fix ASAP. Thanks!
