Delay in printing to screen [message #4254]

I'm running IDL for Windows and want to print information to the screen about the state
of my program, eg my program might contain the lines:

print,'What data file do you want to restore?'
read,datafile
print,'Please wait while restoring data...'
restore,datafile

The problem I have is that the restore procedure, which may take quite a few seconds, is done before the message 'Please wait while restoring data...' is printed to the screen. I'd like it to be printed before the restore procedure is started. I have also
tried using the message command with the keyword 'informational', but experience the
same delay. The Reference Guide says that the !QUIET system variable controls the
printing of informational messages, but I can't find any other references to this
variable or how to change it so that messages are printed immediately to the screen.
Does anyone know if the same thing happens when running IDL under UNIX or if there is
a system variable or 'work around' I can use in Windows to remove this delay time?

Thanks,

Michele Scutter
