To test, fire up VatesSimpleGui, load some data (any will do) and exit the program. It should no longer complain about program aborting or terminating abnormally. This is probably best seen on Linux as I don't know if this behavior was ever seen on Windows.

This has been traced to the code used to destroy all of the sources and the view before the view is switched from one to another. There is an issue that the view is made NULL by ParaView (for reasons I don't understand) before the other sources are destroyed. The crash happens when the view is accessed for information about the other sources. It seems that for on exit behavior, the view class destructor should just do nothing and leave well enough alone. However, the view switching still requires this code or else the old view tries to perform the same operations as the current view. A new function call will be created to handle the mode switch destruction.
