You probably don't want to pop up a dialog for every exception. Some exceptions
can be recovered from with no ill effects to the user. In such cases a pop-up
dialog would be very annoying.
There should however be a way to log exceptions so that it is possible to
diagnose them.

This is a start. Are you saying that a try block and a catch for the Class
Exception in main will catch any exception in the program? All I want the
dialog box to do is print the exception message and maybe tell where to contact
the developers. When the OK button is pressed, then BrailleBlaster should
terminate.
