I started looking at the code today, and I built the addin from source with some extra debugging steps thrown in. I have a couple questions though...
I now have a YacAddIn.dll, but I can't find the same DLL on my system to replace it with the newly built one. I am also concerned about the code not being signed. The source code package had a file reference to your key, Andy. Do I need to create my own key, rebuild the code with it signed, change some XMLs and such, and then reregister the addin with Media Center? If that is the case, how much can I beg you for you to take a look at this for us? Maybe you can throw in a little code snippet to make sure the notification can only appear if it has been more than 30 seconds since the last notification (something like you suggested once before). Thanks.
