	That's funny! I did not reply to this thread AT ALL, AT ANY TIME. The (PARTIAL 
AND OUT OF ORDER) 'quote' below was a response to Willi Kusche's question 'Why 
is the last bit of the allocation map set.'

	If you are using windows, that explains _everything_!!!

	That is the question (of Willi's) that I answered IN A DIFFERENT THREAD.
