Crash happens with some of the apps. InputMultiList list shown then rotate screen and it crashes. Also, when the list pops up and leave it untouched for 5 seconds or more then cancel on the outside will cause it to crash.

Error occurred on line: 753 (Main)

Line 753 code is as follows in "Pause" event and pnlLogView is initialized at "Create" event.
B4X: 
rotDiagReport = pnlLogView.Visible

Adding this will resolve the problem (Sometimes..weird??)
B4X: 
    If pnlLogView.IsInitialized Then                 'added this to prevent crashes.  ??? what happened
        rotDiagReport = pnlLogView.Visible            'DIAGNOSTIC LOG REPORT FOR ROTATION
    End If

Here are couple of errors in the log
