Kill each active IDL window manually, and then at the IDL promot
type "retall" and then "xmanager".
I've tried to use the WIDGET_CONTROL, /RESET feature to kill all
the widgets, but this seems to leave IDL in a strange state. Even
after typing retall and xmanager, widget applications do not start
up correctly.

When the crash occurs, first destroy the widget, then type:
IDL> RETALL ;Gets back to main program level
IDL> XMANAGER ;Causes XMANAGER to clean itself up
This should allow you to rerun the application again and have it respond properly.

Take a look at your terminal window when it is unresponsive, you will probably
see the IDL prompt. If so then just type XMANAGER to start the event
processing.
