Way to reproduce:
Search up a title and make sure you only get one hit on the search.
Click "Details".
Then "Cover".
Click the picture to make it fullscreen.
Then move your finger up for "Next".
Then the whole thing crashes with three exceptions.
First exception with stack:
DVD Profiler Mobile.exe
NullReferenceException

at DVD_Profiler_Mobile.frmFullscreenImage.pbImage_MouseUp()
at System.Windows.Forms.Control.OnMouseUp()

at System.Windows.Forms.Application.Run()
at DVD_Profiler_Mobile.frmStartup.Main()

Click "End" (I guess it's "End", since it's "Avslutt" on my Norwegian phone").
Then the next exception comes:
DVD Profiler Mobile.exe
ObjectDisposedException

at Microsoft.AGL.Common.MISC.HandlerAr()
at System.Windows.Forms.Control.Dispose()
at System.ComponentModel.Component.Dispose()
at DVD_Profiler_Mobile.frmFullscreenImage.Dispose()
at System.ComponentModel.Component.Finalize()

Click "End" another time and a new exception comes:
DVD Profiler Mobile.exe
ObjectDisposedException

at Microsoft.AGL.Common.MISC.HandlerAr()
at System.Windows.Forms.Control.Dispose()
at DVD_Profiler_Mobile.BufferedPanel.Dispose()
at System.ComponentModel.Component.Dispose()
at DVD_Profiler_Mobile.DetailView.Dispose()
at System.ComponentModel.Component.Finalize()

Then click "End" for the last time and then the application exits.

I can reproduce this each time I try this on my HTC HD2.

Actually, it has nothing to do with that.

DVD Profiler Mobile tries to switch to an image that doesn't exist, since I'm trying to move "next" on a list of 1.

The crash comes since the program doesn't check if there is a "next" image BEFORE it switches the image.

I didn't try this, but from the observations so far, if my search resulted in more than one title, it wouldn't crash. I'll see if I can test this on the way to work today.
