Hello Steve, Perhaps you can allow access via WMS Request (if your map is for WMS configured).

Yes, a simple refresh of the same map will, 9 times ot of 10, get rid of the garbage. But then at a random interval it will reappear (but will be different garbage). It's kind of hard for me to "post" the entire app, or allow access, right now i'm afraid so I appreciate it may be hard for anyone to help, I as just fishing for ideas really!
