A similar problem arises when plotting complicated graphics under X,
where IDL sends off the plot commands then merrily continues, but the
output of the commands doesn't appear until IDL returns to the prompt
or to the xmanager.
The solution in that case is to place "WAIT, 0" after the plot command,
which appears to sync everything up, flush buffers, whatever. Maybe
it'll help you under Windoze.
