My birdcam has been working fine for a couple of weeks. This morning, Yawcam had reset to all defaults--streaming port, page designer text, file output location, etc. I had to reconfigure all those to get the system back to the settings I wanted.
I've been trying to get some auto-wakeup and auto-shutdown scripts to work so that I don't have to manually boot and shut down the PC every day. There's a chance the computer didn't shut down properly last night. Even if that were the case, it would imply that Yawcam is somehow resetting the config details when it's started then writing the values when it shuts down.
BTW, the default port of 8081 is the same as the management interface on my Linksys router. My main config change is to pick a different port for the stream so that it could pass through my router. Perhaps you'll choose a different default port for future releases.
