I agree this is a minor issue, but because there is an invalid memory I read I thought it was relevant. I tested with the browser plugin on the latest Firefox, and while it crashes the plugin, it doesn't seem to crash the browser. As I said previously, I will continue to investigate whether I can get some program control, but for now it's only a measly DoS. Regards Pedro
