This is interesting, and suggestive, too. I wonder
if the ability to break into WHILE loops was added
when management of widget programs was taken out of
XManager. Makes sense that you would have to check
back to the command line periodically to see if a
widget event was waiting to be processed. If so, this
would be the first ever evidence of a positive benefit
from allowing users access to the IDL command line
when widget programs were running. :-)

Cheers,

David
