I finally found a way to reproduce a minor issue in BubbleBurst, the application reviewed in my Advanced MVVM book. I fixed the issue, which had to do with bursting a bubble group during an animated undo transition, and updated the source code and download files on CodePlex. If you’re interested in seeing the fix, it’s associated with changeset 43211.
By the way, I would like to thank all of you who have bought Advanced MVVM. I am shocked at how many copies have sold so far. This far exceeds my expectations!
