Just installed 2012.2.629 and was running my app in the emulator to check out the changes (I also had noticed the RadDiagnostics wasn't sending emails and wanted the fix). I am seeing something very strange. Two of the pages in my app have an application bar. One bar has 1 icon plus 3 menu items, the other has 4 icons. The page with the bar with 1 icon leads to the other page. What I'm seeing is that the ApplicationBar on the first page is getting corrupted (the one with the single icon). Putting a break point in the Loaded event I see that this.ApplicationBar actual points to the other page's ApplicationBar instead of its own. Other times this.ApplicationBar is null. I build the ApplicationBar in the constructor of the page, and once created it never changes.
What seems to trigger the problem is on the second page I occasionally hide the ApplicationBar. I set this.ApplicationBar.IsVisible to false in the WindowOpening event of a RadModalWindow, and back to true in the WindowClosed event. The window is always closed before leaving the page. If I don't do this I can go back and forth between the two pages just fine. As soon as I hide and show the ApplicationBar once, the ApplicationBar on the first page gets screwed up.
I do not see this behavior with the older version (2012 Q2), just SP1. It is very odd.
