Thanks Ryan,
I got a little closer, after I edited .actionScriptProperties and changed the "targetPlayerVersion" to 0.0.0, I was able to import and build without a problem and my changes did appear in "WebViewerDemo/bin-debug" folder (and worked when I loaded Webviewer.html).
The 2 problems I have now is:
1. I'm not sure how to put this into production, in webviewer in the flash dir the only swf file is ReaderControl.swf and I don't see that as being created from the SDK build I just did (I see a WebViewer.swf, a frameworkxxx.swf, sparkxxx.swf etc but no ReaderContol.swf).
2. You guys (you I think), created a full screen button for me when I put in a request for feature/work. That's not in the current SDK download. Is there any chance on getting a updated SDK or if its something easy, can you tell me how to add the full screen?
TIA!
