Subject: How to do tail -f with NXStreams ?

Hi,
I'm trying to build an application, which has to read a logfile and to
display it within a ScrollView in a Window.
What I'm doing is:
	aStream = NXMapFile(fn,NX_READONLY);
        [myText readText:aStream];

when I now try to read more from the stream via [myText readText:aStream];,
the View clears as it is supposed to do, but no characters are displayed.

The only possibility I see at the moment is to reopen the file and to 
reread the stream, which takes an enormous amount of time for large files.

Any clues?
