If ShowDVI<#480#><#480#> has been started as a background task, no output is sent
to ``stdout''. This means, that in a case of error, no error messages
appear visibly (in case the ShowDVI<#481#><#481#> screen closes so fast, that you
could not read the message there). Thus it is recommended not to switch
off the logfile and to examine it then. The exact cause of error
is listed there.
If the program crashes uncontrolled, the logfile is unfortunately not
readable anymore. Then you should start it once again in the foreground
to see if at least in the window an error message appears.
In any case, am uncontrollable crash is something so odd, that
you should contact me at once. ( :-) -TT)
But please with detailed information, so that I can reproduce the
error.
