I run a special version of XMANAGER to allow me to have the main
program as part of the event loop. This is required to create
arbitrary variables in a main-level EXECUTE call of the user's text.

I added /NOWAIT (just call widget_event(/nowait) and /FUNC event_func
instead of event_pro) options to xmanager. (Sorry execute preclude
Virtual Machine.)

In this image analysis program I set the hourglass when starting an
action and it disappears when I contol it to zero.
