问题 I'm using dispatchers to update a bound collection from an event. I just ran into a nasty issue where I had two different dispatchers in the same event and it wasn't working. Using the debugger it was completely skipping over the code in the first dispatcher. Putting the entire event in a single dispatcher fixed it.

I can't find any way to allow dropping files into my app. I have set AllowDrop on my elements but it won't listen when I drop files on the app (using split screen).
